Hi Chenxu,

This is causing build error for non x86 builds [1], wrapping the
'ice_tx_done_cleanup_vec()' with #ifdef can solve the error, but instead why not
remove the #ifdef completely.

Would the 'tx_vec_allowed' be set when it is non x86, I think it shouldn't, IF
so #ifdef can go away.

defined but not used [-Werror=unused-function]
 ice_tx_done_cleanup_vec(struct ice_tx_queue *txq __rte_unused,
