Remove race condition between reading of MSR, setting md_savecrit,
and setting MSR. This was most evident with the idle proc running
with interrupts disabled and causing a lockup. Switch over to the
i386 style which does things in the right order.

debug assisted by:  gallatin, and the invaluable KTR option.
