nbd/client: More consistent error messages

Consolidate on using decimal (not hex), on outputting the
option reply name (not just value), and a consistent comma between
clauses, when the client reports protocol discrepancies from the
server.  While it won't affect normal operation, it makes
debugging additions easier.
