media: rkvdec: Fix .buf_prepare
The driver should only set the payload on .buf_prepare if the
buffer is CAPTURE type. If an OUTPUT buffer has a zero bytesused
set by userspace then v4l2-core will set it to buffer length.
If we overwrite bytesused for OUTPUT buffers, too, then
vb2_get_plane_payload() will return incorrect value which might be then
written to hw registers by the driver in rkvdec-h264.c.
[Changed the comment and used V4L2_TYPE_IS_CAPTURE macro]
Fixes: cd33c830448ba ("media: rkvdec: Add the rkvdec driver")
