  In DV mode, when quitting an application, the default drop action
and its resources should be released. The Devx action for the TIR
was not destroyed and it would cause 80B memory leak.

With this commit, in DV mode, the action should be destroyed in the
mlx5_devx_drop_action_destroy() explicitly.
