Subject: [PATCH v2 net-next] net: usb: remove unnecessary get_drvinfo code and driver versions

Many USB network drivers define get_drvinfo functions which add no
value over usbnet_get_drvinfo, only setting the driver name and
version. usbnet_get_drvinfo automatically sets the driver name, and
separate driver versions are now frowned upon in the kernel. Remove all
driver versions and replace these get_drvinfo functions with references
to usbnet_get_drvinfo where possible. Where that is not possible,
remove unnecessary code to set the driver name. Also remove two
unnecessary initializations from aqc111_get_drvinfo, an inaccurate
comment in pegasus.c, and an unused macro in catc.c.
