gpu-compute: Number of TLBs equal to number of CUs
The n_cu variable in GPUTLBConifig.py did not take
the number of CUs into consideration and instead
calculated the number of TLBs using cu_per_sa,
sa_per_complex, num_gpu_complexes. Thus changing
the number of cus (n_cus) and none of the other flags
resulted in a segmentation fault since the required
TLBs were not being instantiated
