Mark Johnston a2d704d19f Avoid unnecessary object locking in vm_page_grab_pages_unlocked(). 
We were needlessly acquiring the object lock to call
vm_page_grab_pages() even when all of the requested pages were looked up
locklessly.  Fix that, stop testing for count == 0 in
vm_page_grab_pages(), and add assertions to help catch this kind of
mistake.
