[PATCH] sctp: Initialize daddr on peeled off socket

[Petr Malat <oss@malat.biz>]

Function sctp_do_peeloff() wrongly initializes daddr of the original
socket instead of the peeled off socket, which makes getpeername()
return zeroes instead of the primary address. Initialize the new socket
instead.

Fixes: d570ee490fb1 ("[SCTP]: Correctly set daddr for IPv6 sockets during peeloff")
