[PATCH v2] app/testpmd: fix releasing action handle flush memory

[Bing Zhao <bingz@nvidia.com>]

The memory of the indirect action handles should be freed after
being destroyed in the flush. The behavior needs to be consistent
with the single handle destroy port_action_handle_destroy().

Or else, there would be some memory leak when closing / detaching a
port without quitting the application. In the meanwhile, since the
action handles are already destroyed, it makes no sense to hold the
indirect action software resources anymore.
