Sure there is. Just kill the session, Ctrl-c or similar.
pg_stop_backup() isn't actually doing anything at that point anymore;
it's just waiting for the files to be archived before returning.

Or fix archive_command, and pg_reload_conf().

BTW, if you want a timeout for that, you can use statement_timeout.
