Jan H. Schönherr 92a8b03cdf x86/mce: Fix possibly incorrect severity calculation on AMD 
[ Upstream commit a3a57ddad0 ]

The function mce_severity_amd_smca() requires m->bank to be initialized
for correct operation. Fix the one case, where mce_severity() is called
without doing so.

Fixes: 6bda529ec4 ("x86/mce: Grade uncorrected errors for SMCA-enabled systems")
Fixes: d28af26faa ("x86/MCE: Initialize mce.bank in the case of a fatal error in mce_no_way_out()")
