x86/apic: Move cpumask and to core code
All implementations of apic->cpu_mask_to_apicid_and() and the two incoming cpumasks to search for the target. Move that operation to the call site and rename it to cpu_mask_to_apicid() Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Cc: Jens Axboe <axboe@kernel.dk> Cc: Marc Zyngier <marc.zyngier@arm.com> Cc: Michael Ellerman <mpe@ellerman.id.au> Cc: Keith Busch <keith.busch@intel.com> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Christoph Hellwig <hch@lst.de> Link: http://lkml.kernel.org/r/20170619235446.641575516@linutronix.de
