We send gratituous packets to let switch to update its mac address
table, this is only done after migration currently because guest may
move to the host with another port connect to switch.
Unfortunately this kind of notification is also needed for continue a
stopped vm as the mac address table entry may not existed because of
aging. This patch solve this by call qemu_announce_self() in
vm_start() instead of in process_incoming_migration(). Through this,
gratituous packets were sent each time when vm starts.
