Xen devel - Jun 2011 - [PATCH][VTD] 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.

It looks like I forgot to attach the patch last Friday.  Jean just encountered
the same problem and send me the same fix.

Ian, can you check it in so no one else will encounter this?  Thanks.

Allen
