dm thin: avoid metadata commit if a pool's thin devices haven't changed
commit 4d1662a30dde6e545086fe0e8fd7e474c4e0b639 upstream.
Commit 905e51b ("dm thin: commit outstanding data every second")
introduced a periodic commit. This commit occurs regardless of whether
any thin devices have made changes.
Fix the periodic commit to check if any of a pool's thin devices have
changed using dm_pool_changed_this_transaction().
