Subject: [PATCH v2 2/2] media: chips-media: wave5: Process ready frames when CMD_STOP sent to Encoder

CMD_STOP being sent to encoder before last job is executed by device_run
can lead to an occasional dropped frame. Ensure that remaining ready
buffers are drained by making a call to v4l2_m2m_try_schedule.
