examples/netmap_compat: fix overflow in ioctl operation

Browse Source 
Compiling the netmap example with clang-3.5 triggered the following
warning:

  compat_netmap.c:783:11: error: overflow converting case value to
    switch condition type (3225184658 to 18446744072639768978)
    [-Werror,-Wswitch]
              case NIOCREGIF:
                 ^
Indeed, an ioctl value should be an unsigned 32 bits, not an int.
