ipv6: Check dest prefix length on original route not copied one in rt6_alloc_cow().
[ Upstream commit bb3c36863e8001fc21a88bebfdead4da4c23e848 ]
After commit 8e2ec639173f325977818c45011ee176ef2b11f6 ("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'.
