IB/hfi1: Ensure dd->gi_mask can not be overflowed

Browse source

As the code stands today the array access in remap_intr() is OK. To
future proof the code though we should explicitly check to ensure the
index value is not outside of the valid range. This is not a straight
forward calculation so err on the side of caution.
