mac802154: llsec: fix incorrect lock pairing
In encrypt, sec->lock is taken with read_lock_bh, so in the error path, we must read_unlock_bh. Signed-off-by: Phoebe Buckheister <phoebe.buckheister@itwm.fraunhofer.de> Reported-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: David S. Miller <davem@davemloft.net>
