Bjørn Mork b701f16dd4 net: qmi_wwan: set correct altsetting for Gobi 1K devices 
commit bd877e4 ("net: qmi_wwan: use a single bind function for
all device types") made Gobi 1K devices fail probing.

Using the number of endpoints in the default altsetting to decide
whether the function use one or two interfaces is wrong.  Other
altsettings may provide more endpoints.

With Gobi 1K devices, USB interface #3's altsetting is 0 by default, but
altsetting 0 only provides one interrupt endpoint and is not sufficent
for QMI.  Altsetting 1 provides all 3 endpoints required for qmi_wwan
and works with QMI. Gobi 1K layout for intf#3 is:

    Interface Descriptor:  255/255/255
      bInterfaceNumber        3
      bAlternateSetting       0
      Endpoint Descriptor:  Interrupt IN
    Interface Descriptor:  255/255/255
      bInterfaceNumber        3
      bAlternateSetting       1
      Endpoint Descriptor:  Interrupt IN
      Endpoint Descriptor:  Bulk IN
      Endpoint Descriptor:  Bulk OUT

Prior to commit bd877e4, we would call usbnet_get_endpoints
before giving up finding enough endpoints. Removing the early
endpoint number test and the strict functional descriptor
requirement allow qmi_wwan_bind to continue until
usbnet_get_endpoints has made the final attempt to collect
endpoints.  This restores the behaviour from before commit
bd877e4 without losing the added benefit of using a single bind
function.

The driver has always required a CDC Union functional descriptor
for two-interface functions. Using the existence of this
descriptor to detect two-interface functions is the logically
correct method.

/* This driver supports wwan (3G/LTE/?) devices using a vendor
* specific management protocol called Qualcomm MSM Interface (QMI) -
* in addition to the more common AT commands over serial interface
* management
*
* QMI is wrapped in CDC, using CDC encapsulated commands on the
* control ("master") interface of a two-interface CDC Union
* resembling standard CDC ECM. The devices do not use the control
* interface for any other CDC messages. Most likely because the
* management protocol is used in place of the standard CDC
* notifications NOTIFY_NETWORK_CONNECTION and NOTIFY_SPEED_CHANGE
*
* Alternatively, control and data functions can be combined in a
* single USB interface.
*
* Handling a protocol like QMI is out of the scope for any driver.
* It is exported as a character device using the cdc-wdm driver as
* a subdriver, enabling userspace applications ("modem managers") to
* handle it.
*
* These devices may alternatively/additionally be configured using AT
* commands on a serial interface
