> 
> The mlx5 PMD allocated the resources of the sample actions, and then
> moved these ones to the destination actions array. The original indices were
> not cleared and the resources were referenced twice in the flow object - as
> the fate actions and in the destination actions array.
> 
> This causes the failure on flow destroy because PMD tried to release the
> same objects twice.
> 
> The patch clears the original indices, add the missed checking for zero and
> eliminates multiple object releasing.
