Bluetooth: Handle specific error for SCO connection fallback
Synchronous Connection Complete event can return error "Connection
Rejected due to Limited resources (0x10)".
Handling this error is required for SCO connection fallback. This error
happens when the server tried to accept the connection but failed to
negotiate settings.
This error code has been verified experimentally by sending a T2 request
to a T1 only SCO listener.
Client dump follows :
