Btrfs: fix mount -o clear_cache,space_cache=v2
We moved the code for creating the free space tree the first time that it's enabled, but didn't move the clearing code along with it. This breaks my (undocumented) intention that `mount -o clear_cache,space_cache=v2` would clear the free space tree and then recreate it.
