stellaris: delay timer_new to avoid memleaks

Browse source 
There is a memory leak when we call 'device_list_properties' with typename = stellaris-gptm. It's easy to reproduce as follow:

  virsh qemu-monitor-command vm1 --pretty '{"execute": "device-list-properties", "arguments": {"typename": "stellaris-gptm"}}'

This patch delay timer_new in realize to fix it.
