drm/i915/mst: Disable transcoder before deleting the payload

Browse source

Bspec tells us that we should disable the transcoder before
deleting the payload. Looks like this has been reversed since
MST support was added.

I suppose this shouldn't matter in practice since the downstream
device shouldn't really do anything with the new payload until
we send the ACT. But I see no compelling reason to deviate from
the bspec sequence regardless.
