MCE: Fix bug of IA32_MCG_STATUS after system reset
Now, if we inject a fatal MCE into guest OS, for example Linux, Linux
will go panic and then reboot. But if we inject another MCE now,
system will reset directly instead of go panic firstly, because
MCG_STATUS.MCIP is set to 1 and not cleared after reboot. This is does
not follow the behavior in real hardware.
This patch fixes this via set env->mcg_status to 0 during system reset.
