Fix a leak in code added in c51f8f94e5b (submodule--helper: run update procedures from C, 2021-08-24), we clobber the "displaypath" member of the passed-in "struct update_data" both so that die() messages in this update_submodule() function itself can use it, and for the run_update_procedure() called within this function.
