net/mlx5: fix memory leak on ASO age close
net/mlx5: fix memory leak on ASO age close

Recent patch introduced the use of ASO flow hit action for age action.
The relevant management struct uses dynamically allocated memory.
This memory was not freed on closing.

This patch adds memory freeing as needed.
