  datapath-windows: Fix nbl cleanup when memory allocation fails

StartNblIngressError should be called only when an NBL hasn't been
modified. In this case the nbl context was initialized. Rely on existing
packet completion mechanism to cleanup the NBL.

Found while testing with DriverVerifier with limited memory setting
enabled.

  datapath-windows: Fix potential deadlock in event subscription

Move the EventQueue lock acquisition after the dispatchLock to prevent a
potential deadlock in port creation pipeline. There could be a case where
a port event could try to take up the Dispatch Lock before the Event Queue
lock and the subscription queue event could take up the event queue lock
before the dispatch lock.

Found while testing with Driver Verifier enabled.
