[dpdk-stable] [PATCH] examples/performance-thread: fix return check

[Jacek Piasecki]

There was a call for thread create function without result check.
Added result check and message printout after failure.

Coverity issue: 143441
Fixes: 433ba6228f9a ("examples/performance-thread: add pthread_shim app")
