kfdtest: Take vram size into account when calculate buffer number.
Vram size is relatively smaller in APU, e.g. 512MB.
Current MMBench doesn't support small vram system.
Running MMBench may have below errors:
[ RUN ] KFDMemoryTest.MMBench
[ ] Found VRAM of 512MB.
[ ] Test (avg. ns) alloc mapOne umapOne mapAll umapAll free
