drivers: timer: nrf_grtc_timer: Fix for random system hangs
d599e2b6705eb removed early return from sys_clock_timeout_handler if
current counter value is less than cc_val. It seems that this return is
needed as after the removal some stress tests which were using system
timers heavily started to hang.
