Well, syzbot's reproducer triggers this issue via USB Raw Gadget API. IIUC this
is a debugging feature and it is possible to have the only raw gadget device.
So when running syzbot's reproducer, 'list_count_nodes(&sdata->local->interfaces)'
is always <= 1. But how this is expected to work for >1 case?
