mm: free up PG_slab
Reclaim the Slab page flag by using a spare bit in PageType. We are
perennially short of page flags for various purposes, and now that the
original SLAB allocator has been retired, SLUB does not use the
mapcount/page_type field. This lets us remove a number of special cases
for ignoring mapcount on Slab pages.
