tools/testing/shared: catch a failed posix_memalign()
posix_memalign() returns zero or a positive error number and never sets
errno, so the checks for a negative return in kmem_cache_alloc_lru() and
kmem_cache_alloc_bulk() is not possible. A failed aligned allocation
carries on with the pointer unset, into the constructor or the memset().
Test for any non-zero return.
