The SLAB_MEM_SPREAD flag is already a no-op as of 6.8-rc1, remove
its usage so we can delete it from slab. No functional change.

Update changelog to make it clearer:
The SLAB_MEM_SPREAD flag used to be implemented in SLAB, which was
removed as of v6.8-rc1, so it became a dead flag since the commit
16a1d968358a ("mm/slab: remove mm/slab.c and slab_def.h"). And the
series[1] went on to mark it obsolete to avoid confusion for users.
Here we can just remove all its users, which has no functional change.

Thanks for the updated text, this is a bit better.
I've updated your commit message with this and will push to Linus next
merge window in a couple of weeks, as you said there's no change so no
reason to submit a patch this late in the cycle.
