Marcelo Ricardo Leitner 38687b56c5 sctp: allow unsetting sockopt MAXSEG ...

RFC 6458 Section 8.1.16 says that setting MAXSEG as 0 means that the user
is not limiting it, and not that it should set to the *current* maximum,
as we are doing.

This patch thus allow setting it as 0, effectively removing the user
limit.
