PATCH 2/3 btrfs cleanup: remove more dead code

rb_node cannot be an ERR_PTR() here so I removed the misleading check. Also I removed some more dead code at the bottom.

It looks like the code from lookup_extent_mapping() may have been copy and pasted into search_extent_mapping()?

This doesn't change anything. Could you put it into linux-next?
