Commit 0e8c36a9fd81 ("Btrfs: fix lots of orphan inodes when the space
is not enough") changed the way transaction reservation is made in
btrfs_evict_node and as a result this function became unused. This has
been the status quo for 5 years in which time no one noticed, so I'd
say it's safe to assume it's unlikely it will ever be used again.
