Patch 1f210080609f2c00b4d1859eb0b363a38838e7d3 ("Remove use of global
'reds' from AgentMsgFilter") introduced a regression. This because
QXLInterface->client_monitors_config was called before returning
from spice_add_interface. Some client of spice-server expect the
spice_add_interface already returned and some state change was done
before client_monitors_config was called.
