IB/mad: Validate MADs for spec compliance
Validate MADs sent by userspace clients for spec compliance with C13-18.1.1 (prevent duplicate requests and responses sent on the same port). Without this, RMPP transactions get aborted because of duplicate packets. This patch is similar to that provided by Jack Morgenstein.
