There's no requirement to suppress probe deferral messages and doing so
makes it harder to debug problems since things just fail silently.  It's
better to work on making the core smarter about probe ordering, for
example by building out the device dependency infrastructure so that it
can be used to avoid trying to probe things when we know there are
unsatisfied dependencies.
