mm/slub: remove the check for NULL kmalloc_caches

Browse source

If the same size kmalloc cache already exists, it should not be created
again. So there is the check for NULL kmalloc_caches before calling the
kmalloc creation function. However, new_kmalloc_cache() itself checks NULL
kmalloc_cahces before cache creation. Therefore, the NULL check is not
necessary in this function.
