[Xen-changelog] [qemu-xen-unstable] passthrough: mask out upper bits in vendor id

commit 5c5295c807583e3cc29fafb3603a8b89dc83edac

    passthrough: mask out upper bits in vendor id
    Making vendor_id u16 eliminates potential bogus upper bits that are
    not part of the actual 16-bit vendor ID.  On some systems, upper bits
    shows up with 0xffff.
