OVS agent doesn't start on Windows because of linux specific import

[Adelina Tuvenie]

Change I6574cef3c95525ace6a98cf968ee159190681394 breaks the OVS Agent on Windows because of this line:

from neutron.agent.linux import polling as linux_polling

This causes the agent to crash with the following trace:

The fix is trivial and consists of implementing InterfacePollingMinimizer for Windows as a empty class and importing polling from common instead of Linux.
