IB/mad: Return EPROTONOSUPPORT when an RDMA device lacks the QP required
We had a script which was looping through the devices returned from ibstat and attempted to register a SMI agent on an ethernet device. This caused a kernel panic for IBoE devices that don't have QP0. Fix this by checking if the QP exists before using it.
