btrfs: Remove WARN_ON in walk_log_tree
The log_root passed to walk_log_tree is guaranteed to have its root_key.objectid always be BTRFS_TREE_LOG_OBJECTID. This is by merit that all log roots of an ordinary root are allocated in alloc_log_tree which hard-codes objectid to be BTRFS_TREE_LOG_OBJECTID. In case walk_log_tree is called for a log tree found by btrfs_read_fs_root in btrfs_recover_log_trees, that function already ensures found_key.objectid is BTRFS_TREE_LOG_OBJECTID. No functional changes. Signed-off-by: Nikolay Borisov <nborisov@suse.com> Reviewed-by: David Sterba <dsterba@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>
