Nit: this is not the normal brace placement.

But what is you diff against anyway?  The one Matthew sent did away
with the VFIO_DEVICE_NEEDS_KVM flags, which does the wrong thing for
zpci, so it can't be that..

Also if we want to do major code movement, it really needs to go into
a separate patch or patches, as the combinations of all these moves
with actual code changes is almost unreadable.
