net/i40e: fix CRC strip enabling

New testpmd will get CRC strip offload from rx_offload_capa. I40evf
cannot disable CRC strip. And in fact, it is enabled by PF. This
patch solves the issue by adding CRC strip flag into rx_offload_capa
in i40e and i40evf.

Fixes: 8b9bd0efe0b6 ("app/testpmd: disable Rx VLAN offloads by default")
