[PATCH] i386: Set MCG_STATUS_RIPV bit for mce SRAR error

[luofei]

In the physical machine environment, when a SRAR error occurs,
the IA32_MCG_STATUS RIPV bit is set, but qemu does not set this
bit. When qemu injects an SRAR error into virtual machine, the
virtual machine kernel just call do_machine_check() to kill the
current task, but not call memory_failure() to isolate the faulty
page, which will cause the faulty page to be allocated and used
repeatedly. If used by the virtual machine kernel, it will cause
the virtual machine to crash
