Yilong Guo 9bbab539de [subgroups][non_uniform_broadcast] Fix broadcasting index generation ...

The subgroup size may not be greater than `NR_OF_ACTIVE_WORK_ITEMS`.
Broadcasting index needs to be reduced in that case.

Otherwise, if subgroup size == `NR_OF_ACTIVE_WORK_ITEMS` == 4, then we
will encounter "divide-by-zero" error when evaluating `bcast_index %
(n - NR_OF_ACTIVE_WORK_ITEMS)`.
