Subject: [PATCH] selftests/resctrl: Return NULL if malloc_and_init_memory()
did not alloc mem

[ Upstream commit 22a8be280383812235131dda18a8212a59fadd2d ]
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")
