Routine Description:
Deregister the ioctl interface. This is called whenever a miniport
instance is halted. When the last miniport instance is halted, we
request NDIS to delete the device object
Arguments:
NdisDeviceHandle Handle returned by NdisMRegisterDevice
Return Value:
NDIS_STATUS_SUCCESS if everything worked ok
