Also this change has been removed in next-net, it is irrelevantt to the pathch.

Missing curly parantheses in the 'if' blocks are causing confusion on which
return patch to take.
the above code is like this:
if (txq->offloads == 0 && ...)
if (txq->tx_rs_thresh <= RTE_IXGBE_TX_MAX_FREE_BUF_SZ && ...)
return ixgbe_tx_done_cleanup_vec(txq, free_cnt);
return ixgbe_tx_done_cleanup_simple(txq, free_cnt); <----- [*]
return ixgbe_tx_done_cleanup_full(txq, free_cnt);
It is not clear, and looks like wrong based on indentation, when to get the [*]
path above.
I will add curly parantheses while merging.
Btw, why we need "#ifdef RTE_IXGBE_INC_VECTOR" here, can't we remove it?

Since 'ixgbe_tx_done_cleanup_vec()' already implemented in this file, instead of
vector specific files, I am removing the ifdef.
So making changes [1] and function becomes [2]. Please validate it in next-net.
