x86/irq: Reorganize the search in assign_irq_vector

Browse source

commit 95ffeb4b5b upstream.

Split out the code which advances the target cpu for the search so we can
reuse it for the next patch which adds an early validation check for the
vectormask which we get from the apic.

Add comments while at it.
