[PATCH RFC 10/12] mm/slab: reduce slabobj_ext memory with allocation profiling disabled

When memory allocation profiling is compiled in but permanently disabled
on boot with (implicit or explicit) "never" parameter, stop allocating
(wasting) memory for the codetag_ref parts of slabobj_ext metadata.
