slab: Remove folio references from __do_krealloc()

As with memcg_slab_post_charge(), we save a call to compound_head()
for large kmallocs.  This has a slight change of behaviour in that
non-vmalloc, non-slab, non-kmalloc pointers will now cause a NULL
pointer dereference rather than a warning.  We could add that back if
really needed.
