Matthew Wilcox (Oracle) 84fbbe2189 mm/rmap: Constify the rmap_walk_control argument ...

The rmap walking functions do not modify the rmap_walk_control, and
page_idle_clear_pte_refs() takes advantage of that to move construction
of the rmap_walk_control to compile time.  This lets us remove an
unclean cast.
