btrfs: add a helper to get the delayed ref node from the data/tree ref

Browse source

We have several different ways we refer to references throughout the
code and it's not consistent and there's a bit of duplication.  In order
to clean this up I want to have one structure we use to define reference
information, and one structure we use for the delayed reference
information.  Start this process by adding a helper to get from the
btrfs_delayed_data_ref/btrfs_delayed_tree_ref to the
btrfs_delayed_ref_node so that it'll make moving these structures around
simpler.
