avcodec/vvc: Fix output and unref a frame which isn't decoding yet

Browse source 
ff_vvc_output_frame is called before actually decoding. It's possible
for ff_vvc_output_frame to select current frame to output. If current
frame is nonref frame, it will be released by ff_vvc_unref_frame.

Fix this by always marking the current frame with
VVC_FRAME_FLAG_SHORT_REF, as is done by the HEVC decoder.
