media: chips-media: wave5: Fix pipeline stall when queuing fails

Browse source

The Wave5 decoder calls v4l2_m2m_job_finish() immediately in device_run()
after submitting frames to firmware. When the firmware completes those
frames and the queue drains to zero, finish_decode() has no active M2M
job to finish, so v4l2_m2m_schedule_next_job() is never called and the
decoder stalls.

Call v4l2_m2m_try_schedule() in finish_decode() when the firmware queue
empties to ensure the framework always schedules the next device_run().
