Eliminate unnecessary checks from vm_pageout_clean(): The page that is
passed to vm_pageout_clean() cannot possibly be PG_UNMANAGED because
it came from the inactive queue and PG_UNMANAGED pages are not in any
page queue. Moreover, PG_UNMANAGED pages only exist in OBJT_PHYS
objects, and all pages within a OBJT_PHYS object are PG_UNMANAGED.
So, if the page that is passed to vm_pageout_clean() is not
PG_UNMANAGED, then it cannot be from an OBJT_PHYS object and its
neighbors from the same object cannot themselves be PG_UNMANAGED.
