avcodec/vp9: Simplify replacing VP9Frame

Browse Source 
ff_thread_progress_replace() can handle a blank ProgressFrame
as src (in which case it simply unreferences dst), but not
a NULL one. So add a blank frame to be used as source for
this case, so that we can use the replace functions
to simplify vp9_frame_replace().
