This fixes a deadlock in gst_vaapiencode_change_state, which was due to srcpad's chain function was locked waiting for available buffers. Since the coded buffers in codedbuf_queue become available after sinkpad consume the encoded frames, Paused -> Ready state change leads to deadlock. Coded buffers are never consumed and marked free, hence gst_vaapiencode_handle_frame waits for available buffers and holds the stream_lock of the srcpad.
