x86/mce: Check whether writes to MCA_STATUS are getting ignored
The platform can sometimes - depending on its settings - cause writes
to MCA_STATUS MSRs to get ignored, regardless of HWCR[McStatusWrEn]'s
value.
For further info see
PPR for AMD Family 19h, Model 01h, Revision B1 Processors, doc ID 55898
at https://bugzilla.kernel.org/show_bug.cgi?id=206537.
Therefore, probe for ignored writes to MCA_STATUS to determine if hardware
error injection is at all possible.
