[PATCH] USB: usbnet driver fixes

Updates to the usbnet driver:

 - Remove a warning when built with Zaurus support but not CDC Ethernet;
   just moves an #ifdef to cover more code

 - Two tweaks to the pseudo-MDLM support:
    * correctly handle _either_ of the two GUIDs
    * ignore a padding bit that doesn't seem necessary

 - Remove ID for one Motorola phone that uses the MDLM stuff.

It also updates the Kconfig helptext to make it clearer that the "Zaurus"
configuration option supports an increasing (sigh) family of nonstandard
peripheral protocols.
