I was about to push the series (except patch 10), but I hit a crash
when passing an invalid option to test-null.sh.

Reproduced with:

Core was generated by

Program terminated with signal SIGSEGV, Segmentation fault.

$1 = 0

rte_eal_cleanup() is called from rte_exit() by testpmd.
But since rte_eal_init() failed at parsing, lcore_config[*].thread_id
are invalid, and we crash on pthread_cancel.
I have no quick idea to fix this, series postponed to rc2.
