quota-class-update fails for default class

[Ollie Leahy]

quota-update-class appears to be broken in the current version of python-cinder-client, using both the v1 and the v2 API's

$ cinder --os-volume-api-version 1 quota-class-update --volumes 20 default
ERROR: 'NoneType' object has no attribute '_info'

$ cinder --os-volume-api-version 2 quota-class-update --volumes 20 default
ERROR: 'Namespace' object has no attribute 'class_name'

    Fixes quota-class-update commands

    The quota-class-update commands for v1 and v2 are both broken,
    Fix v1 by returning result for update method in QuotaClassSetManager,
    fix v2 by changing arg 'class-name' to 'class_name' for consistent
    with v1.
