blk-mq-pci: add a fallback when pci_irq_get_affinity returns NULL
commit c005390374957baacbc38eef96ea360559510aa7 upstream.
While pci_irq_get_affinity should never fail for SMP kernel that
implement the affinity mapping, it will always return NULL in the
UP case, so provide a fallback mapping of all queues to CPU 0 in
that case.
