[meta-arago][kirkstone][PATCH] receipes-multimedia: gstreamer: Increase decode display delay

[Prasanth Babu Mantena]

Increase the number of buffers between the decoder and display to
support smooth streaming of decoded data to downstream pool.
This has been set to ref_frame plus 3 which was 2 before.

 Add checks to release the buffer to downstream pool when returned with
 error flag from the driver. This buffer which registered with driver is
 used a an offset buffer without any new allocation in downstram pool.
+Set buffer offset to ref_frames plus 3.
