[PATCH 2/5] x86/mce/inject: Set the valid bit in MCA_STATUS before error injection

[Smita Koralahalli <Smita.KoralahalliChannabasappa@amd.com>]

MCA handlers check the valid bit in each status register (MCA_STATUS[Val])
and examine the remainder of the status register only if the valid bit is
set.

Set the valid bit in the corresponding MCA_STATUS register if the user
forgets to set it while doing error simulation.
