- Cancel pending user IRPs when we get a IRP_MJ_CLEANUP request

Browse source 
- Previously there was some confusion between IRPs in PendingIrpList and InFlightRequest, InFlightRequest IRPs go from AFD to a TDI transport driver (tcpip) which are sent on behalf of AFD and are cancelled upon socket destruction (IRP_MJ_CLOSE) vs. IRPs in the PendingIrpList which go from user-mode to AFD which are sent of behalf of the user and should be cancelled when handling IRP_MJ_CLEANUP
