media: coda: increment sequence offset for the last returned frame
[ Upstream commit b3b7d96817cdb8b6fc353867705275dce8f41ccc ]
If no more frames are decoded in bitstream end mode, and a previously
decoded frame has been returned, the firmware still increments the frame
number. To avoid a sequence number mismatch after decoder restart,
increment the sequence_offset correction parameter.
