x86/mm: Fix enc_status_change_finish_noop()

enc_status_change_finish_noop() is now defined as always-fail, which
doesn't make sense for noop.

The change has no user-visible effect because it is only called if the
platform has CC_ATTR_MEM_ENCRYPT. All platforms with the attribute
override the callback with their own implementation.
