Subject: [PATCH] testing/selftests/mqueue: Fix mq_perf_tests to free the allocated cpu set

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.
