usbnet: avoid integer overflow in start_xmit
transfer_buffer_length is of type u32. It's therefore wrong to assign it to a signed integer. This patch avoids the overflow. It's worth noting that entry->length here is a long; perhaps it would be beneficial at somepoint to change this to be unsigned as well, if nothing else relies on its signedness for error conditions or the like.
