EDAC/amd64: Drop some family checks for newer systems

mainline inclusion
from mainline-v5.6-rc1
commit dcd01394
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I4MKP4


CVE: NA

--------------------------------

In general, "pvt->umc != NULL" is used to check if the system is Family
17h+. However, there are a few places that are using direct family
checks.

Replace the remaining family checks with a check for "pvt->umc != NULL".
