[0/3] x86/nvmx: attempt to fix interrupt injection

Message

Hello,

This is a fixup of a wrong previous bugfix. It has been tested on the
debina0 osstest host and it fixes the interrupt injection issues seen
there when running the nested HVM tests. I mention this explicitly
because albeit I don't expect it I don't discard it might cause issues
on other boxes with a different set of VMX features.

I've tried to make the patches as small and contained as possible in
order to avoid breaking other stuff.
