Julian Anastasov 0975764684 ipv6: allow PMTU exceptions to local routes
IPVS setups with local client and remote tunnel server need
to create exception for the local virtual IP. What we do is to
change PMTU from 64KB (on "lo") to 1460 in the common case.

Suggested-by: Martin KaFai Lau <kafai@fb.com>
Fixes: 45e4fd2668 ("ipv6: Only create RTF_CACHE routes after encountering pmtu exception")
Fixes: 7343ff31eb ("ipv6: Don't create clones of host routes.")
