[dpdk-dev] No telemetry legacy support print

[Jerin Kollanukkaran]

"No telemetry legacy support " prints pops up on all the default dpdk 
applications now.
Is it worth to print? Since it using direct 'printf', we cannot even disable 
through dynamic logging.
Is possible to remove that print at least, if non legacy telemetry init is 
successful. 
Thoughts?
