ACPI / APEI: Remove spurious GHES_TO_CLEAR check

ACPI / APEI: Remove spurious GHES_TO_CLEAR check

BugLink: https://bugs.launchpad.net/bugs/1822005
ghes_notify_nmi() checks ghes->flags for GHES_TO_CLEAR before going
on to __process_error(). This is pointless as ghes_read_estatus()
will always set this flag if it returns success, which was checked
earlier in the loop. Remove it.
