USB: serial: option: Ignore card reader interface on Huawei E1750

commit eb2addd4044b4b2ce77693bde5bc810536dd96ee upstream.

Hi,

my Huawei 3G modem has an embedded Smart Card reader which causes
trouble when the modem is being detected (a bunch of "<warn>  (ttyUSBx):
open blocked by driver for more than 7 seconds!" in messages.log). This
trivial patch corrects the problem for me. The modem identifies itself
as "12d1:1406 Huawei Technologies Co., Ltd. E1750" in lsusb although the
description on the body says "Model E173u-1"
