app/flow-perf: skip dumps for masked ports

Take into consideration that the user may call portmask for
any run, thus the app should always check if port is needed
to collect and report or not.

Fixes: 070316d01d ("app/flow-perf: add multi-core rule insertion and deletion")
Fixes: d8099d7ecb ("app/flow-perf: split dump functions")
