[PATCH] SCTP: fix IPv4 addr in SCTPv6 accept()/getpeername()

[Dave Johnson]

An accept() call on a SCTPv6 socket that returns due to connection of
a IPv4 mapped peer will fill out the 'struct sockaddr' with a zero
IPv6 address instead of the IPv4 mapped address of the peer.

This is due to the v4mapped flag not getting copied into the new
socket on accept().
