Marcel Holtmann e73439d8c0 Bluetooth: Defer SCO setup if mode change is pending
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.
