Remove the warning for Scheduling Network

when a new port is created, the schedule_network in agentschedulers_db is called.
Since this network may already be hosted, it will directly return None in dhcp_agent_scheduler,
which cause the agentschedulers_db.schedule_network log a warning message.

This is really annoying and making users confused.
And, real warnings are already addressed in the real scheduler function.
which is neutron.scheduler.dhcp_agent_scheduler.ChanceScheduler.schedule by default.
