x86/mce: Fix possibly incorrect severity calculation on AMD
[ Upstream commit a3a57ddad061acc90bef39635caf2b2330ce8f21 ]
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: 6bda529ec42e ("x86/mce: Grade uncorrected errors for SMCA-enabled systems")
Fixes: d28af26faa0b ("x86/MCE: Initialize mce.bank in the case of a fatal error in mce_no_way_out()")
