The documentation for the JSON/qapi type 'UnixSocketAddress' states that the unix socket path field is named 'path'. Unfortunately qemu uses 'socket' in case of the gluster driver (despite documented otherwise). Add logic which will format the correct fields while keeping support of the old spelling.
