[media] v4l: vb2: Set data_offset to 0 for single-plane output buffers

Browse source 
Single-planar V4L2 buffers are converted to multi-planar vb2 buffers
with a single plane when queued. The plane data_offset field is not
available in the single-planar API and must be set to 0 for all output
buffers.
