I wonder what actually caused this check to be inserted. That is, what
could lead to track being NULL that is no longer the case?

I don't know, I cc'd the original patch author about it. IMHO this was never needed because only streams which are added in mxf_add_metadata_stream have their priv_data (track) set to NULL, and those streams are always DATA.
