Timo Völker 4d43ea1319 icmp6: clear csum_flags on mbuf reuse 
When icmp6 sends an ICMPv6 message, it reuses the mbuf of the packet
that triggered the ICMPv6 message and prepends an IPv6 and ICMPv6
header. For a locally generated packet with checksum offloading, the
mbuf still has csum_flags set indicating that a SCTP/TCP/UDP checksum
has to be computed and inserted. Since this not the case anymore,
csum_flags need to be cleared.
