e1000e: register pm_qos request on hardware activation
The pm_qos_add_request call has to register the pm_qos request with the pm_qos
susbsystem before first use of the pm_qos request via
pm_qos_update_request.
As pm_qos changed to use plists there is no benefit in registering and
unregistering the pm_qos request on ifup/ifdown and thus we move the
registering into e1000_open and the unregistering in e1000_close.
This fixes the following warning:
