EDAC/skx_common: Filter out the invalid address

Browse source

Decoding an invalid address with certain firmware decoders could
cause a #PF (Page Fault) in the EFI runtime context, which could
subsequently hang the system. To make {i10nm,skx}_edac more robust
against such bogus firmware decoders, filter out invalid addresses
before allowing the firmware decoder to process them.
