It looks good to me. do_sea() has done all necessary action for SEA, so it
should always return 0,
no matter ghes_notify_sea() return true or false.

In Intel SDM Volume 3B (253669-063US, July 2017), SRAO could be
reported via CMC:
In cases when SRAO is signaled via CMCI the error signature is
indicated via UC=1, PCC=0, S=0.
So we add those known AO MCACODs check in mce_severity().
