In the commit dd52b8ea02 ("Bluetooth: controller: Fix
first connection interval timing"), instead of using just a
tick unit as workaround, microseconds corresponding to a
tick unit was used while calculating the window offset to be
used at the connection update instant. This introduced an
error in scheduling the first event with new connection
parameters, causing supervision timeout of connection update
procedure.

When a peer master performed a PHY update procedure with no

Fix Connection Parameter Request Procedure's Connection
Update Procedure initiation to calculate the offset rather
than selecting offsets from an out-of-bound memory area.
The symptoms of the bug was noticed as a supervision timeout
due to use of incorrect offset communicated to peer and a
wrong offset used in scheduling the connection events.

When the peer slave rejects a Connection Parameter Request
Procedure, the controller proceeds to perform a Connection
Update Procedure without clearing the procedure timer that
causes the connection to terminate eventually. This is
fixed by clearing the procedure timeout when the Connection
Update Procedure completes.

If a peer master role has support for Connection Parameter
Request Procedure set in its supported features but would
send an Extended Reject Ind as response to the procedure
then the controller incorrectly initiated a Connection
Update Procedure which is not permitted in a slave role.
This would lead to connection timeout after the used instant
in the invalid Connection Update Procedure.
This is fixed by initiating a Connection Update Procedure
only if in a master role.

Issuing HCI reset command while having connections sometimes
hung the controller.
ll_reset supplied invalid stop ticker id to role_disable
when trying to stop all connections. Connection role does
not utilize stop ticker. The invalid ticker id supplied
referenced memory outside the pool of tickers and based on
what the content is in RAM there, the controller would hang
trying to stop connections.
Fixed by not calling the ticker_stop interface with invalid
ticker ids.

Earlier design captured AA twice in the first Rx in a slave

During testing it was discovered that directed advertising
timeout is missing implementation to handle the timeout
happening while next event is already in preparation.
The consequence was that after the event ticker expired,
the counter is shutdown, stalling the setup PPI from
starting the erroneous advertising, leaving the controller
in an invalid hung state.
This has been fixed by correctly handling the cases, stop
between prepare and event, and stop inside radio advertising
event. The fix takes care of putting the radio active
callback and HF clock in the correct states.

Fixes an assert during connection establishment when the
initiator overflows the initiator window in time while
sending the CONNECT_IND PDU. The actual window is one low
frequency tick less, hence corrected the check that permits
the transmission of CONNECT_IND PDU inside the initiator
window.
Symptom was, stopping of the scanner's ticker succeeds on
connection establishment, but next interval prepare was
already run when continuous scanning was used, breaking the
design, hence there was an assert.
