This still needs the extra vmread for IDT_VECTORING_INFO_FIELD for every

Having thought about it some more I'm quite happy with the current code. It will mean that we continue to work even if we choose to vmexit on #GP (which we still do on debug builds).

If you can come up with cheap code to detect lost ExtIRQs that'd be nice but it's really not very critical at all.
