Navdeep Parhar 09b0b8c058 Do not generate illegal mbuf chains during IP fragment reassembly. Only 
the first mbuf of the reassembled datagram should have a pkthdr.

This was discovered with cxgbe(4) + IPSEC + ping with payload more than
interface MTU.  cxgbe can generate !M_WRITEABLE mbufs and this results
in m_unshare being called on the reassembled datagram, and it complains:

panic: m_unshare: m0 0xfffff80020f82600, m 0xfffff8005d054100 has M_PKTHDR
