MFC r350335:
Simplify the handling of superpages in pmap_clear_modify(). Specifically,
if a demotion succeeds, then all of the 4KB page mappings within the
superpage-sized region must be valid, so there is no point in testing the
validity of the 4KB page mapping that is going to be write protected.
Deindent the nearby code.
