David S. Miller bb3c36863e ipv6: Check dest prefix length on original route not copied one in rt6_alloc_cow(). ...

After commit 8e2ec63917 ("ipv6: don't
use inetpeer to store metrics for routes.") the test in rt6_alloc_cow()
for setting the ANYCAST flag is now wrong.

'rt' will always now have a plen of 128, because it is set explicitly
to 128 by ip6_rt_copy.

So to restore the semantics of the test, check the destination prefix
length of 'ort'.
