MFC revision 1.58
  Correct contigmalloc2()'s implementation of M_ZERO.


The remaining two problems are corrected by the rewrite of 
contigmalloc(9) that is already in HEAD, and thus will appear in FreeBSD 
7.0.  However, I cannot foresee the rewrite being MFCed to FreeBSD 6.x.

Unless I hear an objection, I'm going to close this PR in a few days.
