Mark Johnston 0ffec1b03d Clean up reassignbuf() and buf_vlist_remove() a bit. 
- Convert panic() calls to INVARIANTS-only assertions.  The PCTRIE code
  provides some of the same protection since it will panic upon an
  attempt to remove a non-resident buffer.
- Update the comment above reassignbuf() to reflect reality.
