[PATCH 09/10] net: usb: smsc95xx: fix handling of multiple packets per urb

[Ahmad Fatoum]

len is the actual length of the USB bulk transfer, while size is the
length of the current packet, which may be different if we have multiple
packets per transfer.

We don't seem to run into this in barebox, perhaps because of our MTU,
but let's fix it anyway.
