xfrm6: Fix a offset value for network header in _decode_session6
When a network-layer header has multiple IPv6 extension headers, then offset
for mobility header goes wrong. This regression breaks an xfrm policy lookup
for a particular receive packet. Binding update packets of Mobile IPv6
are all discarded without this fix.
