Mark Johnston 1e2b3e6f92 Allow vm_page_free_prep() to dequeue pages without the page lock. 
This is a step towards being able to free pages without the page
lock held.  The approach is simply to add an implementation of
vm_page_dequeue_deferred() which does not assert that the page
lock is held.  Formally, the page lock is required to set
PGA_DEQUEUE, but in the case of vm_page_free_prep() we get the
same mutual exclusion for free by virtue of the fact that no
other references to the page may exist.

No functional change intended.
