I don't think this is the best solution.

First, it leaves the check_provider of the per-domain structures we use
in responders around while duplicating the same functionality in the DP.
At the very least, the patch should remove the "check_provider" tests from
the existing loops.

What I think would be even better solution is to
    1) in the RC just fix the subdomains code so that it shortcuts or
    doesn't run at all for LOCAL lookups.
    2) The work we'll be doing later on #1126 would merge all the loops
    into one common place.

This approach would have the benefit of all the checks being done at one
common place, so that we don't forget to add them like we did in the
subdomains case and at would be faster at the same time because it
wouldn't even contact the DP at all, much like it's done now in the
separate loops.
