You are right, they are not in the same scope. Yet it is not exactly
like ipv4 case. Line 1116 declares the prefix and line 1122 the sa,
while in the ipv6 case both variables are declared in 1078. The change
makes the code look more similar by declaring the ipv6 sa inside the
for just like the ipv4.
