[dpdk-dev] [PATCH v3] examples/l3fw-power: do not exit on power lib init failure

[Radu Nicolau <radu.nicolau@intel.com>]

Do not exit the application if power library fails to initialize
or high performance cores configuration cannot be used - this was the
behavior of the application before the patch that added the high/regular
performance option and also this is the normally expected behavior, the
application can be used with no power options, i.e. test framework.

Fixes: f88e7c175a68 ("examples/l3fwd-power: add high/regular perf cores options")
