vaapidecodebin: try to get display from decoder

Browse source 
Rather than create a dummy display, if none has propagated as a context, we
should try to get the one from vaapidecode.

As the bin is already in READY state, the vaapidecode should be also in that
state. That means that the contexts have been negotiated, and it should have
already a display.
