Herton R. Krzesinski a979558448 ipc,sem: remove uneeded sem_undo_list lock usage in exit_sem() ...

After we acquire the sma->sem_perm lock in exit_sem(), we are protected
against a racing IPC_RMID operation.  Also at that point, we are the last
user of sem_undo_list.  Therefore it isn't required that we acquire or use
ulp->lock.
