[PATCH] genirq/affinity: Assign default affinity to pre/post vectors

Generally, irq_create_affinity_masks() assign default affinity to pre/ post vectors correctly. However, it ignore the case that there are only pre/post vectors (when nvecs == affd->pre_vectors + affd->post_vectors) and return NULL. This case usually happens when nvecs = 1 (e.g. in nvme driver when
