Do not use xform_ipip as decapsulation fallback.
xform_ipip was used as fallback with low priority for IPIP encapsulated packets that were decrypted. In some cases it can decapsulate packets, that it shouldn't. This leads to situations, when wrong configurations are magically working. Also it can propagate wrong ingress interface and this can break security. Now we redesigned the IPSEC code and IPIP encapsulation is called directly from ipsec_output, and decapsulation is done in the ipsec_input with m_striphdr.
