[PATCH] net/mlx5: fix the timing of releasing drop action

[Bing Zhao <bingz@nvidia.com>]

When creating the drop action Devx object, the global counter set
is also used as in the regular or hairpin queue creation.

The drop action should be destroyed before the global counter set
release procedure. Or else, the counter set object is still
referenced and cannot be released successfully. This would cause
the counter set resources to be exhausted after starting and stopping
the ports repeatedly.
