[PATCH] app/testpmd: fix flow creation parsing

[Alexander Kozyrev <akozyrev@nvidia.com>]

A pattern template creation shares the parsing mechanism with
a simple flow creation. The pattern template creation only consists
of pattern items while the flow creation continues with actions.
The parsing mechanism now accommodates both cases and allows to stop
at the item end token, which should not happen for the flow creation.
Fix parsing mechanism to differentiate between these two cases.
