A userspace process will be typically blocked, waiting on the request file descriptor. Returning the OUTPUT (src) buffer will wake-up such processes, who will immediately attempt to dequeue the CAPTURE buffer, only to find it's still unavailable. Therefore, change v4l2_m2m_buf_done_and_job_finish returning the CAPTURE (dst) buffer first, to avoid signalling the request file descriptor prematurely, i.e. before the CAPTURE buffer is done. When the request API is not used, this change should have no impact.
