PCI: Restore PCI_MSIX_FLAGS_BIRMASK definition
commit c9ddbac9c89110f77cb0fa07e634aaf1194899aa upstream.
09a2c73ddfc7 ("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.
