[PATCH] kernel/time/posix-cpu-timers: Remove useless call to check_dl_overrun

[Juri Lelli]

check_dl_overrun is used to send a SIGXCPU to users that asked to be
informed when 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.
