genirq/affinity: Don't return with empty affinity masks on error
When the allocation of node_to_possible_cpumask fails, then
irq_create_affinity_masks() returns with a pointer to the empty affinity
masks array, which will cause malfunction.
Reorder the allocations so the masks array allocation comes last and every
failure path returns NULL.
