r8152: fix unknown device for choose_configuration

BugLink: https://bugs.launchpad.net/bugs/2060097

[ Upstream commit 46590b545df636aea0f9f7f2100d9963c0af5824 ]

For the unknown device, rtl8152_cfgselector_choose_configuration()
should return a negative value. Then, usb_choose_configuration() would
set a configuration for CDC ECM or NCM mode. Otherwise, there is no
usb interface driver for the device.
