[dpdk-stable] [PATCH] app/testpmd: fix latencystats deinit on signal

[agupta3 at marvell.com]

From: Amit Gupta <agupta3 at marvell.com>

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 onlyif latencystats is enabled.

Fixes: 62d3216d6194 ("app/testpmd: add latency statistics calculation")
