commit 45bc6098a3e279d8e391d22428396687562797e2 upstream.

IA32_MCG_STATUS.RIPV indicates whether the return RIP value pushed onto
the stack as part of machine check delivery is valid or not.

Various drivers copied a code fragment that uses the RIPV bit to
determine the severity of the error as either HW_EVENT_ERR_UNCORRECTED
or HW_EVENT_ERR_FATAL, but this check is reversed (marking errors where
RIPV is set as "FATAL").

Reverse the tests so that the error is marked fatal when RIPV is not set.
