nfp: fix esp-tx-csum-offload doesn't take effect

Browse Source 
When esp-tx-csum-offload is set to on, the protocol stack shouldn't
calculate the IPsec offload packet's csum, but it does. Because the
callback `.ndo_features_check` incorrectly masked NETIF_F_CSUM_MASK bit.

Fixes: 57f273adbcd4 ("nfp: add framework to support ipsec offloading")
