In btrfs_put_root() we're freeing a btrfs_root's 'node' and 'commit_root'
extent buffers manually via kfree(), while we're using
free_root_extent_buffers() in the free_root_pointers() function above.
free_root_extent_buffers() also NULLs the pointers after freeing, which
mitigates potential double frees.
