crosvm: aarch64: fix lack of shifting for base_dev_pfn

Browse source 
This is a pfn (page-frame number) not a raw address, so we need to
shift it right by 12.

BUG=chromium:840048
TEST=manual test on kevin with virtio wayland and --disable-sandbox,
should not get "failed to recv from vfd: VmBadResponse" message
