Allocations from GPU nodes will return VRAM, not system memory. Only non-paged allocation from GPU nodes is supported. System memory can only be allocated from CPU nodes (usually node 0). The HostAccess flag is no longer used to distinguish the memory type. It only indicates, whether the memory is mapped for CPU access. Maintain compatibility with broken KfdTests by returning system memory for paged-memory requested from GPU nodes. Change-Id: I514defede735f55e6de436f41944125b6f2c4ccf
