compositor: Prevent startup crash when hdcp mode is set on display

Browse source 
We can startup with the display already in type1 content protection mode.
When this happens, we call weston_output_dirty_paint_nodes() on a display
that hasn't yet been enabled. The paint node list isn't initialized yet,
so we crash.

We don't actually need to touch the paint nodes here anyway, as
weston_output_damage() ensures a repaint if the ourput is enabled, and
weston_output_dirty_paint_nodes() just forces calculation of things
unrelated to protection, and we'll override most of that in
maybe_replace_paint_node() if necessary when we get there.

Just drop the weston_output_dirty_paint_nodes() call to stop the
crash.
