The commit f77f0aee4da4 ("net: use core MTU range checking in USB NIC
drivers") introduce a common MTU handling for usbnet. But it's missing
the necessary changes for smsc95xx. So set the MTU range accordingly.
This patch has been tested on a Raspberry Pi 3.
Fixes: f77f0aee4da4 ("net: use core MTU range checking in USB NIC drivers")
