Bluetooth: Better locking when tearing down an HCI connection.

Browse Source 
Restarting Riva will abruptly disconnect the hci device, which can
tear down the hci_conn struct on one processor while RFCOMM code
is running on another. This would keep l2cap_chan_del from being
executed while RFCOMM is in the middle of using a socket.
