USB: Add LPM quirk for Surface Dock GigE adapter

commit ea261113385ac0a71c2838185f39e8452d54b152 upstream.

Without USB_QUIRK_NO_LPM ethernet will not work and rtl8152 will
complain with

    r8152 <device...>: Stop submitting intr, status -71

Adding the quirk resolves this. As the dock is externally powered, this
should not have any drawbacks.
