sctp: use SCTP_FUTURE_ASSOC for SCTP_RECONFIG_SUPPORTED sockopt
Check with SCTP_FUTURE_ASSOC instead in sctp_set/getsockopt_reconfig_supported, it's compatible with 0. It also adjusts some code to keep a same check form as other functions. Signed-off-by: Xin Long <lucien.xin@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
