The selftest "mqueue/mq_perf_tests.c" use CPU_ALLOC to allocate CPU set. This cpu set is used further in pthread_attr_setaffinity_np and by pthread_create in the code. But in current code, allocated cpu set is not freed. Fix this by adding CPU_FREE after its usage is done.
Good find.

CPU_ALLOC() is called very early on in main() and there are a few error paths that exit without calling CPU_FREE. This change doesn't fully fix the problem. Review the other exit paths where CPU_FREE is needed. thanks, -- Shuah
