avcodec/pthread_frame: Don't prematurily presume frame-threading

Several of our decoders support both frame- as well as slice-threading;
in case of the latter avctx->internal->thread_ctx points to
a SliceThreadContext, not to a frame-thread PerThreadContext.
So only treat avctx->internal->thread_ctx as the latter after
having checked that frame-threading is active.
