        // enable interface.
        //
        // Pnp can unregister the interface in following cases:
        // 1. The driver is uninstalled, and re-installed
        //    In this case, the stack is torn down but the PDO is not
        //    deleted. Pnp deletes the interface registration, however WDF
        //    doesn't delete the interface structure because it is deleted as
        //    part of PDO deletion in destructor. When the driver is re-installed
        //    Pnp sends another query resource requirements irp and WDF needs to
        //    re-register at this time.
        //
        // 2. Pnp couldn't find a driver and loaded a NULL driver while
        //    waiting for reinstall to happen from WU. This is similar to case above
        //    except that the pnp activities are transparent to user.
        //    In this case, PDO was never started. However it did get
        //    the query resource requirements irp and therefore its interface
        //    was registered by WDF. Pnp deleted the interface registration
        //    when installing NULL driver. When pnp finally finds a driver from
        //    WU, it sends another query resource requirement irp. At this time,
        //    WDF needs to re-register.
        //
        // In both the above cases, WDF has to re-register (and free previous
        // sym link) when query resource requirements irp arrives again. Note
        // that Pnp doesn't delete the interface registration during disable,
        // s/w surprise-removal, or resource rebalance. In case of resource
        // rebalance, query resource requirement irp is sent after stop, and
        // WDF will end up registering again even though pnp did not unregister
        // the interface. This is fine because kernel API for registration
        // allows multiple calls to register, and in case registration already
