xfrm6_tunnel: Fix spi check in __xfrm6_tunnel_alloc_spi
gcc warn this:
net/ipv6/xfrm6_tunnel.c:143 __xfrm6_tunnel_alloc_spi() warn:
always true condition '(spi <= 4294967295) => (0-u32max <= u32max)'
'spi' is u32, which always not greater than XFRM6_TUNNEL_SPI_MAX
because of wrap around. So the second forloop will never reach.
