app/testpmd: fix tunnel offload flows cleanup

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.
