x86_64: Correct the start address of device memory
When guest ram >= 4G, as mmio hole exists in ram GuestMemory, GuestMemory->end_addr() is larger than memsize, if memsize is used as start address of device memory, device memory will overlap with Guest ram. This patch use GuestMemory->end_addr() as the start address of device memory. BUG=None TEST=Boot vm with guest memory above 4G, and enable vGPU, and run vGPU benchmark.
