[PATCH net-next] i40e: remove inline directive

[YueHaibing]

Fixes follow gcc warning:

drivers/net/ethernet/intel/i40e/i40e_ethtool.c: In function '__i40e_add_stat_strings':
drivers/net/ethernet/intel/i40e/i40e_ethtool_stats.h:193:20: error: function '__i40e_add_stat_strings' can never be inlined because it uses variable argument lists

Fixes: 8fd75c58a09a ("i40e: move ethtool stats boiler plate code to i40e_ethtool_stats.h")
