Dan Williams 5c1fcbfe4a mtk-legacy: read IMSI if CPIN response is an error 
Some older MTK-based phones (Tecno T528 NEW) reply to +CPIN with
an error but are (obviously) unlocked, otherwise they wouldn't
be able to boot up to the point of talking to a computer. Since
they are actually unlocked they will happily give out the IMSI
even if +CPIN errors.

To work around the +CPIN issue treat the device as unlocked if we
can successfully read the IMSI.
