  Move and add missing Tx offloads checks to Tx prepare stage.
Keep absolutely required checks in Tx burst to avoid spoil of
memory and segmentation faults.

There are few checkpatches.sh warnings since positive errno is
used inside driver.

The patch series depends on [1] and should be applied only after it.
[1] is acked by Olivier and was acked by Konstantin Ananyev at RFC
stage saying that more testing is required.
