pcim_alloc_irq_vectors() and pcim_alloc_irq_vectors_affinity() are created for
pci device drivers which rely on the devres machinery to help cleanup the IRQ
vectors.

It might be worth adding some details on why we need the is_msi_managed
flag in the first place vs just doing conventional devm_add_action_or_reset()
with pci_free_irq_vectors().
