Furthermore, these branches were actually leaking the bt_conn if the

To limit the device_found function calls, passive scanning can
take advantage of Filter_Duplicates feature. For now, the stack
will be informed only if some new device will be found.
This solution requires a check if scan filter is used while adding
new address to connect to (bt_connect_le). If filter duplicates
is used (by active scan or passive scan), the scan should be
restarted to refresh scan results.

This fix prevents from sending dummy buffer to kill tx fiber
if this fiber didn't started.
Tx fiber is started during transition from BT_CONN_CONNECT state
(for outgoing connections) or BT_CONN_DISCONNECTED (incoming)
to BT_CONN_CONNECTED state.
So the only states that have tx fiber running are BT_CONN_CONNECTED
and BT_CONN_DISCONNECT and only transitions from these states
should be taken into account.

if enabled and then starts active scan.
So "if (dev.scan_enable)" check can be moved to trigger_scan to avoid

Part of General Connection Establishment Procedure.
Active scanning is enabled by task and has higher priority than
passive scan. If passive scan is running and task wants to enable
scan (active) scanning will be restarted in active mode. Passive
scan is enabled implitly while app calls bt_connect_le.
Instead of directly call hci_le_create_conn, it is called from
device_found if addr obtained from advertisement matches address
we want to connect. App calling bt_stop_scanning can only stop
active scan.

This state will be used for connection establishment during passive scan.
This additional state is necessary, because only one connection can be
in BT_CONN_CONNECT state (LE Create Connection has been sent).
It's because the LE Create Connection Cancel looks for connection in this
state (we cannot look by address, if some controllers respond with
LE Create Connection with address set to 00:00:00:00:00:00).
If connection is BT_CONN_CONNECT_SCAN state it means that we wait for
an advertisement from remote to send LE Create Connection and then we
can change the bt_conn state to BT_CONN_CONNECT.
