hrtimer: Unconfuse switch_hrtimer_base() a bit

#endif

/*

 * Switch the timer base to the current CPU when possible.

 * We switch the timer base to a power-optimized selected CPU target,

 * if:

 *	- NO_HZ_COMMON is enabled

 *	- timer migration is enabled

 *	- the timer callback is not running

 *	- the timer is not the first expiring timer on the new target

 *

 * If one of the above requirements is not fulfilled we move the timer

 * to the current CPU or leave it on the previously assigned CPU if

 * the timer callback is currently running.
