We want to use qemuDomainFindGraphics in the qemuDomainUpdateDeviceConfig in
a future patch. So adjust its parameter.

We can change vnc password by using virDomainUpdateDeviceFlags API with
live flag. But it can't be changed with config flag. Error is reported as
below.
error: Operation not supported: persistent update of device 'graphics' is not
supported
This patch supports the vnc/spice auth arguments changed with config flag.

I'd rather add the flag to the 'flags' variable initialization. (It has no
effect on formatting other devices anyway).
We can just free the old device and replace it with the new one, like we do
for DEVICE_NET. (This will also make it work for other graphics types)
