i40e: fix max frame size

Browse Source 
In FreeBsd driver, the max frame size is changed to MTU, but not
keep the default value defined in DataSheet. When DPDK runs on that
NIC, the configured value is not expected.
This patch sets the max frame size to default when initialization.

Fixes: 4861cde46116 ("i40e: new poll mode driver")
