sctp: fix ignoring asoc_id for tcp-style sockets on some setsockopts

This is a patchset to fix ignoring asoc_id for tcp-style sockets on
some setsockopts, introduced by SCTP_CURRENT_ASSOC of the patchset:

  [net-next,00/24] sctp: support SCTP_FUTURE/CURRENT/ALL_ASSOC
  (https://patchwork.ozlabs.org/cover/1031706/)

As Marcelo suggested, we fix it on each setsockopt that is using
SCTP_CURRENT_ASSOC one by one by adding the check:

    if (sctp_style(sk, TCP))
        	xxx.xxx_assoc_id = SCTP_FUTURE_ASSOC;

so that assoc_id will be completely ingored for tcp-style socket on
setsockopts, and works as SCTP_FUTURE_ASSOC.
