app/testpmd: fix latency stats deinit on signal

On receiving signal, testpmd showing warning as
"LATENCY_STATS: failed to remove Rx/Tx callback"
because rte_latencystats_uninit is called without
checking if latencystats is enabled or not.

After this fix, rte_latencystats_uninit will be
called only if latencystats is enabled.
