[PATCH] genirq: Honor user provided affinity

[Shay Drory]

Currently, whenever user is providing affinity for an IRQ, genirq layer
is ignoring it and assigning the default affinity for the IRQ.
Fix it by honor the user input.

Fixes: 45ddcecbfa94 ("genirq: Use affinity hint in irqdesc allocation")
