tipc: fix compile error when IPV6=m and TIPC=y
When IPV6=m and TIPC=y, below error will appear during building kernel
image:
net/tipc/udp_media.c:196:
undefined reference to `ip6_dst_lookup'
make: *** [vmlinux] Error 1
As ip6_dst_lookup() is implemented in IPV6 and IPV6 is compiled as
module, ip6_dst_lookup() is not built-in core kernel image. As a
result, compiler cannot find 'ip6_dst_lookup' reference while
compiling TIPC code into core kernel image.
But with the method introduced by commit 5f81bd2e5d80 ("ipv6: export a
stub for IPv6 symbols used by vxlan"), we can avoid the compile error
through "ipv6_stub" pointer to access ip6_dst_lookup().
Fixes: d0f91938bede ("tipc: add ip/udp media type")
