Yeah, when I wrote that I was relying on the fact that all the
valid bits in a short-format descriptor are also valid in the
long-format mask, so correct guest software won't care (the
other bits are UNK/SBZP). However the implementation side
of UNK/SBZP requires us to treat the bits as RAZ/WI, so this
patch is correct.
