IB/hfi1: Correct MulticastMask/CollectiveMask info to SMA output

Browse Source 
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.
