btrfs: do not leak reloc root if we fail to read the fs root
commit ca1aa2818a53875cfdd175fb5e9a2984e997cce9 upstream. If we fail to read the fs root corresponding with a reloc root we'll just break out and free the reloc roots. But we remove our current reloc_root from this list higher up, which means we'll leak this reloc_root. Fix this by adding ourselves back to the reloc_roots list so we are properly cleaned up.
