btrfs: handle ENOENT in btrfs_uuid_tree_iterate
If we get an -ENOENT back from btrfs_uuid_iter_rem when iterating the
uuid tree we'll just continue and do btrfs_next_item(). However we've
done a btrfs_release_path() at this point and no longer have a valid
path. So increment the key and go back and do a normal search.
