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. Reviewed-by: Sebastian Sanchez <sebastian.sanchez@intel.com> Signed-off-by: Michael J. Ruhl <michael.j.ruhl@intel.com> Signed-off-by: Dennis Dalessandro <dennis.dalessandro@intel.com> Signed-off-by: Doug Ledford <dledford@redhat.com>
