    vkernel - Fix if_vke
    
    * The vkernel device driver threads are cothreads and do not have
      any per-cpu data.
    
    * Fix recent stat counter changes which attempted to access per-cpu data
      from a cothread.  This fixes a vkernel SIGILL by virtue of the trap()
      code being called recursively on trap's own attempt to access mycpu,
      until its stack runs out.
