app/flow-perf: fix encap/decap actions

[ upstream commit 83f9be1 ]

When using decap actions it's been set to the data to decap
into the encap_data instead of decap_data, as a results we end
up with bad encap and decap data in many cases.

Fixes: 0c8f1f4 ("app/flow-perf: support raw encap/decap actions")
