net: smsc95xx: Fix MTU range

[ Upstream commit 85b18b02 ]

The commit f77f0aee ("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.
