  Reduce the limit of vnodes on i386 when ZFS is loaded to 3/4 of the original
  value, so we don't run out of KVA. The default vnodes limit fits better for
  UFS, but ZFS allocated more file system specific memory for a vnode than UFS.
  Don't touch vnodes limit if we detect it was tuned by system administrator
  and restore original value when ZFS is unloaded.
  This isn't final fix, but before we implement something better, this will
  help to stabilize ZFS under heavy load on i386.
