There is an intercept for WBINVD and INVD in SVM so we don't

The bios (at least bochs bios) does have wbinvd, so this ought to work.
Weird. For some reason the Windows 7 XP emulation was executing wbinvd
which caused an nested intercept for the host level and the rip was not
advanced. So the nested guest did not advance and just produces wbinvd
intercepts all the time.
Has the guest enabled wbinvd interception? Perhaps not, so kvm has to
emulate wbinvd in the nested guest context, which is likely the only
case that we're called to do this. So the problem might be in emulating
within the nested guest.
