If the DSA master fails to probe for whatever reason, then DSA devices will continue on as if nothing is wrong. This can cause incorrect behavior. In particular, on sandbox, dsa_sandbox_probe attempts to access the master's private data. This is only safe to do if the master has been probed first. Fix this by probing the master after we look it up, and bailing out if we get an error.
