[dpdk-stable] [PATCH] app/testpmd: fix tunnel offload flows

[Gregory Etelson]

Tunnel offload model requires application to obtain PMD related flow
items or actions to construct a flow rule. These elements acquire
internal PMD flow resources that must be explicitly released.

The patch destroys tunnel offload PMD resources after flow creation
failure.

Fixes: 1b9f274623b8 ("app/testpmd: add commands for tunnel offload")
