SVN rev 223984 on 2011-07-13 18:35:47Z by marius
PCIB_ALLOC_MSIX() may already fail on the first pass, f.e. when the PCI-PCI
bridge is blacklisted. In that case just return from pci_alloc_msix_method(),
otherwise we continue without a single MSI-X resource, causing subsequent
attempts to use the seemingly available resource to fail or when booting
verbose a NULL-pointer dereference of rle->start when trying to print the
IRQ in pci_alloc_msix_method().
