sit: don't print ip6rd_prefix as integer in sit_dump_details()
First of all, inet_ntop() has no reason to fail (ever). As long
as the input arguments point to valid data and family is not bogus.
But when it fails, we cannot pass a 'struct in6_addr' to "%x"
either, so just don't do that.
Same for printing ip6rd_relay_prefix as AF_INET. If our addr-to-str
method fails, we don't want to come up with something fancy. Otherwise,
we'd just implement a inet_ntop() that does not fail.
