posix-timers: Remove "it_signal = NULL" assignment in itimer_delete()
itimer_delete() is invoked during do_exit(). At this point it is the last thread in the group dying and doing the clean up. Since it is the last thread in the group, there can not be any other task attempting to lock the itimer which means the NULL assignment (which avoids lookups in __lock_timer()) is not required. The assignment and comment was copied in commit 0e568881178ff ("[PATCH] fix posix-timers to have proper per-process scope") from sys_timer_delete() which was/is the syscall interface and requires the assignment. Remove the superfluous ->it_signal = NULL assignment.
