sctp: Catch bogus stream sequence numbers
sctp: Catch bogus stream sequence numbers

Since our TSN map is capable of holding at most a 4K chunk gap,
there is no way that during this gap, a stream sequence number
(unsigned short) can wrap such that the new number is smaller
then the next expected one.  If such a case is encountered,
this is a protocol violation.
