Subject: drm/dp-mst: Remove debug WARN_ON

From: Daniel Vetter <daniel.vetter@ffwll.ch>

commit 42639ba554655c280ae6cb72df0522b1201f2961 upstream.

Apparently been in there since forever and fairly easy to hit when
hotplugging really fast. I can do that since my mst hub has a manual
button to flick the hpd line for reprobing. The resulting WARNING spam
isn't pretty.
