Borislav Petkov 4b1e84276a x86/mce/AMD: Collect error info even if valid bits are not set 
The MCA banks log error info into MCA_ADDR, MCA_MISC0, and MCA_SYND even
if the corresponding valid bits are not set:

"Error handlers should save the values in MCA_ADDR, MCA_MISC0,
and MCA_SYND even if MCA_STATUS[AddrV], MCA_STATUS[MiscV], and
MCA_STATUS[SyndV] are zero."

Do so by setting those bits so that code down the MCE processing path
doesn't need to be changed.
