If ICMP6 message with "Packet Too Big" is received after send SCTP DATA,
kernel panic will occur when SCTP DATA is send again.
This is because of a bad dest address when call to skb_copy_bits().
The messages sequence is like this:
Endpoint A Endpoint B
<------- SCTP DATA (size=1432)
ICMP6 message ------->
(Packet Too Big pmtu=1280)
<------- Resend SCTP DATA (size=1432)
------------kernel panic---------------
