[PATCHv2 3/3] x86/mm: Fix enc_status_change_finish_noop()

From: Kirill A. Shutemov
Date: Fri May 26 2023 - 08:02:48 EST


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

The change doesn't have user-visible effect because it only gets
called if the platform has CC_ATTR_MEM_ENCRYPT. All platforms with
the attribute override the callback with own implementation.
