[PATCH] net/mlx5/hws: fix range definer error recovery

[Gregory Etelson]

PMD did not assign rte_errno value after it discovered an error in
matcher range parameters.
As a result, the calling function was not notified about the fault.

The patch assigns EINVAL to rte_errno if matcher range definition was
invalid.

Fixes: 9732ffe13bd6 ("net/mlx5/hws: add range definer creation")
