Btrfs: try to cleanup delayed refs while freeing extents
When extents are freed, it is likely that we've removed the last delayed reference update for the extent. This checks the delayed ref tree when things are freed, and if no ref updates area left it immediately processes the delayed ref. Signed-off-by: Chris Mason <chris.mason@oracle.com>
