Bug description:
[Description]
Commit a97955844807 ("ipc,sem: remove uneeded sem_undo_list lock usage
in exit_sem()") removes a lock that is needed. This leads to a process
looping infinitely in exit_sem() and can also lead to a crash.
[Test case]
Using the reproducer found in [1] is fairly easy to reach a point where
one of the child processes is looping infinitely in exit_sem between
for(;;) and if (semid == -1) block, while it's trying to free its last
sem_undo structure which has already been freed by freeary().
Once commit a97955844807 ("ipc,sem: remove uneeded sem_undo_list lock
usage in exit_sem()") the issue is not reproducible any more.
