sctp: remove reconf_enable from asoc
asoc's reconf support is actually decided by the 4-shakehand negotiation, not something that users can set by sockopt. asoc->peer.reconf_capable is working for this. So remove it from asoc. Signed-off-by: Xin Long <lucien.xin@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
