[ofw] Access Violation while running ND test over winverb

[Uri Habusha]

Following is some information I take from the debugger. Hopefully it will help. 

Please let me know if mini dump will help.

In the event that's reported, what is the value of port_number?

This would be pEvent->port_number in WvDeviceEventHandler(), or ev->element.port_num in ca_event_handler().
