qmi_wwan: add another Lenovo EM74xx device ID

[ Upstream commit 486181bc ]

In their infinite wisdom, and never ending quest for end user frustration,
Lenovo has decided to use a new USB device ID for the wwan modules in
their 2017 laptops.  The actual hardware is still the Sierra Wireless
EM7455 or EM7430, depending on region.
