usbatm patch for D-Link DSL-200

Kernel BUG

The system is an alix2d2 acting as my Internet router through an USB ADSL modem (DLink DSL200); xusbatm is driving the modem, but it needs a patched version of usbatm (patch was written by Roman Kagan). I've been using this setup since November 2011 (kernel 2.6.36 or 2.6.37), regularly updating the kernel without trouble, so I think this is a regression.

The problem only occurs when killing pppd or br2684ctl (done in a script when connection is lost), otherwise the system works fine:

usbatm patch for D-Link DSL-200

This is the patch written by Roman so that DSL-200 can be used with xusbatm.
