  Teach umastat about the variable-length array of per-CPU caches at the end
  of struct uma_zone.  It is declared as an array of size [1], but then
  sized at run-time by UMA to include room for mp_maxid+1 CPUs.  We have to
  copy the uma_zone first at the declared structure size, then check to make
  sure it's not an internal zone before copying the larger size (UMA
  internal zones don't use per-CPU caches).  This fixes umastat for SMP.
