As it was just unnecessary duplicated information already stored in the 'per_transfer' struct and that's around mostly anyway. The duplicated pointer caused problems when the code flow was aborted before the dupe was filled in and could cause a NULL pointer access. Reported-by: Brian Carpenter Fixes #4807 Closes #4810
