From: Filipe Manana <fdman...@suse.com>
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.
