I'm not sure if you have seen my last comment internally about this patch.
I don't understand why we need these pci_msix_vec_count() followed by
conditional at all.
Perhaps we may simple drop all these and supply flag directly?
But OTOH, I don't know the initial motivation, so, the above patch is
non-intrusive and keeps original logic.
