PATCH 13/23 : Expand XFRM_MAX_DEPTH for routing header and destination options header.

XFRM_MAX_DEPTH is a limit of transformation states to be applied to the same flow. Two extension headers are used by Mobile IPv6 transformation. Based on MIPL2 kernel patch.

Since I suggest to eliminate XFRM_ADVANCED, we should do "6" always here if that is what is needed.
