ctdb-recoverd: Remote IP validation can't cause a takeover run

Remote IP validation is only called when a takeover run is about to
happen anyway, so don't bother flagging one.  Given that a takeover
run isn't being triggered, also drop the test that checks if takeover
runs are disabled.  These are the only uses of the rec argument, so
drop it.

One possible further simplification would be to remove this function
because it doesn't accomplish anything.  However, it is worth leaving
it as a reminder that remote IP validation should be done properly at
some time in the future.
