If there is pending critical or machine check interrupt then guest
would like to capture it when guest enable MSR.CE and MSR_ME respectively.
Also as mostly MSR_CE and MSR_ME are updated with rfi/rfci/rfmii
which anyway traps so removing the the paravirt optimization for MSR.CE
and MSR.ME.

It's only not safe for e500mc and above, right? E500v2 and book3s should be fine.
