sb_edac: avoid decoding the same error multiple times
Whenever the extended error reporting is active, multiple MCEs will be generated for the same event, which will lead to multiple repeated errors to be reported. So check ADDRV and only decode the error if the MCE address is valid. Signed-off-by: Aristeu Rozanski <arozansk@redhat.com> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
