    kern_memio - fix check for zerodev to fix memory mappings
    
    * Change iszerodev() to check against a saaved cdev_t returned by
      the make_dev creating /dev/zero instead of relying on some
      major/minor magic.
    
    * This fixes a problem when running mono, which caused a segfault
      on memset().
