Mark Johnston 70e68b19a4 Handle trashed queue pointers in vm_page_acquire_unlocked(). 
vm_page_acquire_unlocked() relies on type-stability of vm_page
structures and assumes that the listq linkage pointers always point to a
vm_page or are NULL.  QUEUE_MACRO_DEBUG_TRASH breaks that assumption, so
add an explicit check for a trashed queue pointer before dereferencing.
