media: cedrus: Allow using the current dst buffer as reference
It was reported that some cases of interleaved video decoding require using the current destination buffer as a reference. However, this is no longer possible after the move to vb2_find_timestamp because only dequeued and done buffers are considered. Add a helper in our driver that also considers the current destination buffer before resorting to vb2_find_timestamp and use it in MPEG-2.
