kernel - Fix improper OOM process kill when no swap configured

* The avail_shortage calculation used by the pageout demon to track
  whether enough pages could be retired had a degenerate case which
  caused the demon to improperly believe that the machine was out of
  memory when it wasn't.

* Generally would only happen if no swap was configured.
