posix-cpu-timers: Remove useless call to check_dl_overrun()
check_dl_overrun() is used to send a SIGXCPU to users that asked to be
informed when a SCHED_DEADLINE runtime overruns occur.
The function is called by check_thread_timers() already, so the call in
check_process_timers() is redundant/wrong (even though harmless).
Remove it.
Fixes: 34be39305a77 ("sched/deadline: Implement "runtime overrun signal" support")
