`ED_fileselect_get_asset_params` would only return actual data pointer when file browser is in ASSET mode. Calling that whole section only makes sense if filebrowser is in asset mode anyway. Regression introduced in rBf6c5af3d4753 I think. @Severin committing this fix now as this is a fairly critical bug for the studio, feel free to revert and do proper fix if this one is not the best solution.
