ip6_vti: use IS_REACHABLE to avoid some compile errors
Naresh reported some compile errors: arm build failed due this error on linux-next 20200713 and 20200713 net/ipv6/ip6_vti.o: In function `vti6_rcv_tunnel': ip6_vti.c:(.text+0x1d20): undefined reference to `xfrm6_tunnel_spi_lookup' This happened when set CONFIG_IPV6_VTI=y and CONFIG_INET6_TUNNEL=m. We don't really want ip6_vti to depend inet6_tunnel completely, but only to disable the tunnel code when inet6_tunnel is not seen. So instead of adding "select INET6_TUNNEL" for IPV6_VTI, this patch is only to change to IS_REACHABLE to avoid these compile error.
