8b8c610821 avcodec/g2meet: Replace fake allocation avoidance for framebuf 
framebuf is only allocated when the new width/height are larger than the old
but nothing sets the old so its always allocated.
Use av_fast_mallocz() instead.

031c9601d0 lavc/pthread_frame: avoid leaving stale hwaccel state in worker threads 
This state is not refcounted, so make sure it always has a well-defined
owner.

Remove the block added in 091341f2ab, as
this commit also solves that issue in a more general way.
