ipv6: fix dereference of rt6_ex before null check error
Currently rt6_ex is being dereferenced before it is null checked
hence there is a possible null dereference bug. Fix this by only
dereferencing rt6_ex after it has been null checked.
Detected by CoverityScan, CID#1457749 ("Dereference before null check")
Fixes: 81eb8447daae ("ipv6: take care of rt6_stats")
