IB/hfi1: Correct MulticastMask/CollectiveMask info to SMA output
The FM uses the values of MulticastMask and CollectiveMask to
determine the number of bits for net masks. The current values of
0 and 0 are incorrect. The values should be 4 and 1. Updated the
necessary code to reflect the specified values.
