CDC registers to the table-creation hook (before_create_column_family) to add a second table - the CDC log table - to the same keyspace. The handler function (on_before_update_column_family() in cdc/log.cc) wants to retrieve the keyspace's definition, but that does NOT WORK if we create the keyspace and table in one operation (which is exactly what we intend to do in Alternator to solve issue #9868) - because at the time of the hook, the keyspace does not yet exist in the schema. It turns out that on_before_update_column_family() does not REALLY need the keyspace. It needed it to pass it on to make_create_table_mutations() but that function doesn't use the keyspace parameter passed to it! All it needs is the keyspace's name - which is in the schema anyway and doesn't need to be looked up. So in this patch we fix make_create_table_mutations() to not require the unused keyspace parameter - and fix the CDC code not to look for the keyspace that is no longer needed.
