[PATCH 3/3] Bluetooth: Synchronize SCO/eSCO connection requests to ACL state

[Ron Shaffer]

Certain headsets such as the Motorola H350 will reject SCO and eSCO
connection requests while the ACL is transitioning from sniff mode
to active mode. Add synchronization so that SCO and eSCO connection
requests will wait until the ACL has fully transitioned to active mode.

Yes. My apologizes. In a daze, I inappropriately gave the incorrect list for my To:
address.

Sorry for the inconvenience, and thanks for the reminder.
