jbd2: remove wrong sb->s_sequence check

commit e6eff39dd0fe4190c6146069cc16d160e71d1148 upstream.

Journal emptiness is not determined by sb->s_sequence == 0 but rather by
sb->s_start == 0 (which is set a few lines above). Furthermore 0 is a
valid transaction ID so the check can spuriously trigger. Remove the
invalid WARN_ON.
