nucleus: Move xnarch_set_irq_affinity out of intrlock
There is no need to hold intrlock while setting the affinity of the
to-be-registered IRQ. Additionally, we have troubles with MSI code that
can use Linux locks from within this service. So move the affinity
adjustment out of the critical section.
