NFC: Fix sleeping in atomic when releasing socket
nfc_llcp_socket_release is calling lock_sock/release_sock while holding
write lock for rwlock. Use bh_lock/unlock_sock instead.
BUG: sleeping function called from invalid context at net/core/sock.c:2138
in_atomic(): 1, irqs_disabled(): 0, pid: 56, name: kworker/1:1
4 locks held by kworker/1:1/56:
Pid: 56, comm: kworker/1:1 Not tainted 3.5.0-999-nfc+ #7
