Bluetooth: switch to lock_sock in SCO
Since sco_sock_timeout is now scheduled using delayed work, it is no longer run in SOFTIRQ context. Hence bh_lock_sock is no longer necessary in SCO to synchronise between user contexts and SOFTIRQ processing. As such, calls to bh_lock_sock should be replaced with lock_sock to synchronize with other concurrent processes that use lock_sock.
