  Log:
  Check when M_PREPEND returns an empty mbuf.
  
  This is just toe-dipping.  There are so many instances like this
  across the source base that more work needs to be done on it.
  
  I have added /* XXX-MBUF */ comments in places where I could not
  add checks for empty mbufs; this is helpful for future work because
  it is a potential error point.
  
  It is better to put a comment than panic() messages because it can
  be used when the mbuf allocator is rewritten or is taught how to
  handle memory starvation situations.
