When a Bluetooth device is powered down while RFCOMM connections are open, there are race conditions where RFCOMM tries to use an HCI connection after the data structures have been deleted. Since the powerdown procedure runs in process context, it is possible to lock sockets before accessing them to close connections. This change adds that locking, which will serialize socket access between processors during powerdown.
