Pull more btrfs updates from David Sterba:
"This removes unused code of free space caching, disabled in 7.3
(commit 545e560a5b0f: "btrfs: disable v1 space cache").
It's been the original free space cache feature, superseded by free
space tree (4.5) and mkfs default since 5.15. The grace period was
sufficiently long, backward compatibility still exists with a
performance impact, effectively as if mounted with '-o nospace_cache'"
