Refactor fragile msg macro W and W2 to not burry return control flow.
Instead, have them accept and assign a return paramter leaving the return control flow up to the caller. Clean up otherwise misleading returns present even after "NOT REACHED" comments. Change-Id: I0861921f73ab65d55b95eabd27514f0129152723 Signed-off-by: Jon Loeliger <jdl@netgate.com>
