Btrfs: Do snapshot deletion in smaller chunks. Before, snapshot deletion was a single atomic unit. This caused considerable lock contention and required an unbounded amount of space. Now, the drop_progress field in the root item is used to indicate how far along snapshot deletion is, and to resume where it left off. Signed-off-by: Chris Mason <chris.mason@oracle.com>
