[PATCH 40/42] netfilter: ip6table_mangle: Fix set-but-unused variables.

[PATCH 40/42] netfilter: ip6table_mangle: Fix set-but-unused variables.

[David Miller]

The variable 'flowlabel' is set but unused in ip6t_mangle_out().

The intention here was to compare this key to the header value after
mangling, and trigger a route lookup on mismatch.

Make it so.
