#1297433 — [PATCH char-misc-next] misc: mic: return proper error code

On error we are supposed to return negative error code but here we
missed giving the nagative sign. It was never a problem because the
pointer returned from scif_add_mmu_notifier() was never tested. But even
though we should be returning negative error.
