genirq: Fix null pointer reference in irq_set_affinity_hint()
The recent set_affinity commit by me introduced some null
pointer dereferences on driver unload, because some drivers
call this function with a NULL argument. This fixes the issue
by just checking for null before setting the affinity mask.
Fixes: e2e64a932556 ("genirq: Set initial affinity in irq_set_affinity_hint()")
