USB: Gadget Ethernet: Re-enable Jumbo frames. 



commit eea52743 upstream

Fixes: <b3e3893e> ("net: use core MTU range checking")
which patched only one of two functions used to setup the
USB Gadget Ethernet driver, causing a serious performance
regression in the ability to increase mtu size above 1500.
