Fix CUDA barrier init crash when num_consumers < NumThreadsPerWarpGroup
Previously, integer division caused num_consumer_warpgroups_per_cluster to be 0
when params.num_consumers (e.g., 32) was less than NumThreadsPerWarpGroup (128),
leading to a compiler failure during barrier initialization. Changed to round-up
division to ensure a minimum value of 1.
