[PATCH] net/i40e: remove redundant judgment in fdir parse

[Kaiwen Deng]

if (eth_spec && eth_mask &&
	       next_type == RTE_FLOW_ITEM_TYPE_END) {
            ...
            if (next_type == RTE_FLOW_ITEM_TYPE_VLAN || ...) {
            ...
            }
...
}

Clearly, that condition in the inner "if" is always "false".

This commit will remove the redundant judgment.
