Remove dependency on CONFIG_BT_ACL_FLOW_CONTROL and use CONFIG_BT_L2CAP_RX_MTU always to set L2CAP RX MTU. The ATT MTU is set from two different KConfig options depending on if CONFIG_BT_ACL_FLOW_CONTROL is enabled, which makes it a confusing option and hard to provide a conf file that supports multiple board configurations. This changes the behavior when CONFIG_BT_ACL_FLOW_CONTROL and CONFIG_BT_BUF_RX_LEN was used to set the L2CAP RX MTU, and by extension the ATT MTU.

Number of buffers available for fragments of TX buffers. Warning:
|
|
setting this to 0 means that the application must ensure that
|
|
queued TX buffers never need to be fragmented, i.e. that the
|
|
controller's buffer size is large enough. If this is not ensured,
|
|
and there are no dedicated fragment buffers, a deadlock may occur.
|
|
In most cases the default value of 2 is a safe bet.
