avcodec/bsf/dts2pts: fix binary tree invariant violation on selective dec_poc Modifying the keys of a sorted structure, be that a tree or other can lead to changes in the ordering and undefined behavior. It can also lead to collisions with existing keys. All these cases need to be handled unless there is a bug elsewhere that would prevent them.
