Subject: [PATCH] sctp: label accepted/peeled off sockets

Accepted or peeled off sockets were missing a security label (e.g.
SELinux) which means that socket was in "unlabeled" state.

This patch clones the sock's label from the parent sock and resolves the
issue (similar to AF_BLUETOOTH protocol family).
