[dpdk-dev] [PATCH] examples/performance-thread: fix - cleanup before exit

[Ian Betts]

 Fixes: 433ba6228f9a77a9b5f4 ("add pthread_shim app")

 The patch fixes an inverted return value in the
 cond_destroy and cond_init APIs of the pthread shim
 example.

 These APIs are now demonstrated in the sample app by
 having the mutexes and condition variables
 explicitly destroyed before the appplication terminates.
