usb: gadget: prevent potenial null pointer dereference on skb->len
An earlier fix partially fixed the null pointer dereference on skb->len by moving the assignment of len after the check on skb being non-null, however it failed to remove the erroneous dereference when assigning len. Correctly fix this by removing the initialisation of len as was originally intended.
