Logical error in flavors unset_keys method

[zhangjialong]

In novaclient/v1_1/flavors.py unset_keys method,

    def unset_keys(self, keys):
        """
        Unset extra specs on a flavor.

        :param flavor: The :class:`Flavor` to unset extra spec on
        :param keys: A list of keys to be unset
        """
        for k in keys:
            return self.manager._delete(
                            "/flavors/%s/os-extra_specs/%s" % (
                            base.getid(self), k))

Only first key could be remove and unset because of the key word return.

    Logical error in flavors unset_keys method

    When we want to unset multi keys of flavor
    extra data, only first key can be removed
    because of the key word named 'return'.
    To fix it, remove the return key word
