Btrfs: Tune the automatic defrag code
1) Forced defrag wasn't working properly (btrfsctl -d) because some cache only checks were incorrect. 2) Defrag only the leaves unless in forced defrag mode. 3) Don't use complex logic to figure out if a leaf is needs defrag Signed-off-by: Chris Mason <chris.mason@oracle.com>
