OMAPDSS: DSSCOMP: register early callback at suspend

Zero composition queued at suspend doesn't need to
wait to be released, as there's actually nothing to display.

Releasing composition after it's programmed is enough, also
in case of manually updated displays composition callback
never gets called, so queue is stuck and dsscomp can't
properly resume.
