media: coda: improve decoder job finished debug message 

Print a single line containing the following information:
 - which frame was decoded, including its type,
 - if no frame was decoded, the reason (code) why
 - which decoded frame was returned, copied out by either rotator or VODA,
 - if no frame was returned, the reason (code) why, and
 - the output queue sequence number, which is only useful in case
   each queued coded buffer corresponds to exactly one frame.
