genirq/affinity: Don't return with empty affinity masks on error
commit 0211e12dd0a5385ecffd3557bc570dbad7fcf245 upstream.
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.
Fixes: 9a0ef98e186d ("genirq/affinity: Assign vectors to all present CPUs")
