IPC: cleanup some code and wrong comments about semundo list managment
Some comments about sem_undo_list seem wrong.
About the comment above unlock_semundo:
"... If task2 now exits before task1 releases the lock (by calling
unlock_semundo()), then task1 will never call spin_unlock(). ..."
This is just wrong, I see no reason for which task1 will not call
spin_unlock... The rest of this comment is also wrong... Unless I
miss something (of course).
Finally, (un)lock_semundo functions are useless, so remove them
for simplification. (this avoids an useless if statement)
