This looks good to me. If Keith can point to a use case for magic or
hidden nsids we'll have to find a bypass for them, but this certainly
is the right short term fix:
'Flush' is the only command from the spec where specifying all namespaces
might be desirable. Otherwise, I can't disclose vendor specific behavior
to gain concensus on operating within spec, silly as this desire may
seem. Why empower the driver to make a feature unreachable?
