sanify unused ReportMirrorFailure a tiny bit

Calling the (non-existent) reporter multiple times for the same error
with different codes for the same error (e.g. hashsum) is a bit strange.
It also doesn't need to be a public API. Ideally that would all look and
behave slightly different, but we will worry about that at the time this
is actually (planed to be) used somewhere…
