Alan Cox 2e9f4a698d Ensure that vm_object_deallocate() doesn't dereference a stale object 
pointer: When vm_object_deallocate() sleeps because of a non-zero
paging in progress count on either object or object's shadow,
vm_object_deallocate() must ensure that object is still the shadow's
backing object when it reawakens.  In fact, object may have been
deallocated while vm_object_deallocate() slept.  If so, reacquiring
the lock on object can lead to a deadlock.
