[PATCH 02/18] fwd: Comparing rule can be const

[David Gibson <david@gibson.dropbear.id.au>]

This pointer stepping through the array of existing rules can be const.
For some reason cppcheck doesn't catch this at the moment, but does with
certain changes we're looking at for the dynamic configuration client.
