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.
