vfio-pci: Use PCI_MSIX_TABLE_BIR, not PCI_MSIX_FLAGS_BIRMASK
PCI_MSIX_FLAGS_BIRMASK is mis-named because the BIR mask is in the Table Offset register, not the flags ("Message Control" per spec) register. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Acked-by: Alex Williamson <alex.williamson@redhat.com>
