i40e: add missing kernel-doc argument
i40e: add missing kernel-doc argument

The following kernel-doc arguments for their respective functions are
missing:

1) @cd_type_cmd_tso_mss for i40e_tso();
2) @cd_type_cmd_tso_mss for i40e_tsyn();
3) @tx_ring for i40e_tx_enable_csum().

Add them all for the kernel-doc requirement.
