Btrfs: remove rb_node field from the delayed ref node structure
After the last big change in the delayed references code that was needed for the last qgroups rework, the red black tree node field of struct btrfs_delayed_ref_node is no longer used, so just remove it, this helps us save some memory (since struct rb_node is 24 bytes on x86_64) for these structures.
