[PATCH] app/testpmd: fix flow list for async flows

[Alexander Kozyrev <akozyrev@nvidia.com>]

Flows created with the new asynchronous Flow API lack attributes
(direction, priority, group number). These attributes are part of
a template table for flows created via rte_flow_async_create().

When testpmd tries to list all the flows it accesses flow
attributes via pointer and crashes. Save flow attributes during
the template table creation and use them in the "flow list" output.

Fixes: ecdc927b99 ("app/testpmd: add async flow create/destroy operations")
