[PATCH v1 2/3] staging: media: ipu3: Return buffers outside of needless locking

[Max Staudt]

In imgu_vb2_start_streaming()'s error path, imgu_return_all_buffers()
is outside the streaming_lock and after the call to
video_device_pipeline_stop().

Let's apply the same order in imgu_vb2_stop_streaming() as well.
