slab: Warn on duplicate cache names when DEBUG_VM=y
Duplicate slab cache names can create havoc for userspace tooling that
expects slab cache names to be unique [1]. This is a reasonable
expectation.
Sadly, too many duplicate name problems are out there in the wild, so
simply warn instead of pr_err() + failing the sanity check.
[ vbabka@suse.cz: change to WARN_ON(), see the discussion at [2] ]
