From: Fenghua Yu <fenghua.yu@intel.com>

malloc_and_init_memory() in fill_buf isn't checking if memalign()
successfully allocated memory or not before accessing the memory.

Check the return value of memalign() and return NULL if allocating
aligned memory fails.

Fixes: a2561b12fe39 ("selftests/resctrl: Add built in benchmark")
