commit c9ddbac9c8 upstream.
09a2c73ddf ("PCI: Remove unused PCI_MSIX_FLAGS_BIRMASK definition")
removed PCI_MSIX_FLAGS_BIRMASK from an exported header because it was
unused in the kernel. But that breaks user programs that were using it
(QEMU in particular).
Restore the PCI_MSIX_FLAGS_BIRMASK definition.
