posix-timers: check ->it_signal instead of ->it_pid to validate the timer
Impact: clean up, speed up
->it_pid (was ->it_process) has also a special meaning: if it is NULL,
the timer is under deletion or it wasn't initialized yet. We can check
->it_signal != NULL instead, this way we can
- simplify sys_timer_create() a bit
- remove yet another check from lock_timer()
- move put_pid(->it_pid) into release_posix_timer() which
runs outside of ->it_lock
