pc: fix possible NULL pointer dereference in pc_machine_get_device_memory_region_size()
QEMU will crash when device-memory-region-size property is read if ms->device_memory
wasn't initialized yet.
Crash can be reproduced with:
$QEMU -preconfig -qmp unix:qmp_socket,server,nowait &
./scripts/qmp/qom-get -s qmp_socket /machine.device-memory-region-size
Instead of crashing return 0 if ms->device_memory hasn't been initialized.
