[PATCH] genirq/affinity: remove unused arg when building aff mask

[Minwoo Im]

When building affinity masks, the struct irq_affinity *affd is not
needed because irq_create_affinity_masks() has already given a cursored
current vector after pre_vectors via "curvec".

This patch removes unused argument for irq_build_affinity_masks() and
__irq_build_affinity_masks().  No functions changes are included.
