PCI/msi: fix the pci_alloc_irq_vectors_affinity stub


[ Upstream commit 83b4605b0c16cde5b00c8cf192408d51eab75402 ]

We need to return an error for any call that asks for MSI / MSI-X
vectors only, so that non-trivial fallback logic can work properly.

Also valid dev->irq and use the "correct" errno value based on feedback
from Linus.
