Konstantin Belousov e65919f9fc Do not restart the scan in vm_object_page_clean() on the object
generation change if requested mode is async. The object generation is
only changed when the object is marked as OBJ_MIGHTBEDIRTY. For async
mode it is enough to write each dirty page, not to make a guarantee that
all pages are cleared after the vm_object_page_clean() returned.
