Roshi isn't a perfect Jinchuriki so no Son Goku would not snap him out of it, plus the genjutsu is in itself sort infinite as long as the giant clam is in the area and alive, so Roshi would only get caught up in it again. Also Kisame's water release was shown very briefly(as in they showed a small part of the battle the first time around) to counteract his Lava release before his capture.

Gengetsu wins.
