[11/38] tick-common: fix wrong check in tick_check_replacement()

tick_check_replacement() returns if a replacement of clock_event_device is
possible or not. It does this as the first check:

	if (tick_check_percpu(curdev, newdev, smp_processor_id()))
		return false;

This looks wrong as we are returning false when tick_check_percpu() cpu returned
true. Probably Thomas forgot '!' here in his commit: 03e13cf5e ?

Fix it by placing a '!' before tick_check_percpu().
