Modified Files:
        src/sys/dev/usb: ugen.c

Log Message:
reading usbdi.c it looks like usbd_get_config_descriptor() can actually
return NULL, so check for this.
I got NULL pointer dereference here with a device showing:
[   303.732632] ugen0: autoconfiguration error: setting configuration index 0 failed
