[PATCH v2 11/13] mm/slab: reduce slabobj_ext memory with allocation profiling disabled

["Vlastimil Babka (SUSE)" <vbabka@kernel.org>]

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.
