Re: AVStream: DispatchShutdown handler

First, why do you think you need to prevent device removal? And why do you
think you need to handle IRP_MJ_SHUTDOWN?

Anyways to stop AVStream device removal you should implement
KSDEVICE_DISPATCH::QueryRemove. It is a simple delegate for
IRP_MN_QUERY_REMOVE_DEVICE, which is what you should be using to reject
device removal attempt.
