To service requests, the driver maps grant references provided by the
frontend. In this process, errors may be encountered. In one case an
error encountered earlier might be discarded by later processing,
resulting in the caller assuming successful mapping, and hence
subsequent operations trying to access space that wasn't mapped. In
another case internal state would be insufficiently updated, preventing
safe recovery from the error.
