parselogs.py: Add amd_nb error to x86_common whitelist
This has always silently failed on hardware without AMD Northbridge,
and a recent kernel patch made it not silent. It would be ideal to only
whitelist the error for genericx86 MACHINEs and disable the CONFIG
option that enables it in intel-* MACHINEs, but in order to disable
this configuration option we would have to enable EXPERT and
DEBUG_KERNEL, which we don't want. Instead just whitelist it on all
x86 MACHINEs.
Fixes [YOCTO #10261].
