6.13-stable review patch. If anyone has any objections, please let me know.

From: Jan Kara jack@suse.cz
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.
