ECR #304775 - Optimize oclBandwidthTest from nVidia SDK
- Cache pinned memory, since the benchmark sends the same transfer in a single batch. Thus we could avoid pin/unpin
- Swap SDMA engine allocation order. Blit manager allocates a queue on device, thus the first app queue was getting the paging second SDMA.
