IB/rdmavt/hfi1/qib: Use the MGID and MLID for multicast addressing

Browse Source 
The Infiniband spec defines "A multicast address is defined by a
MGID and a MLID" (section 10.5).

The current code only uses the MGID for identifying multicast groups.
Update the driver to be compliant with this definition.
