mm/slab_common.c: check kmem_create_cache flags are common
Verify that kmem_create_cache flags are not allocator specific. It is
done before removing flags that are not available with the current
configuration.
The current kmem_cache_create removes incorrect flags but do not
validate the callers are using them right. This change will ensure that
callers are not trying to create caches with flags that won't be used
because allocator specific.
