    Fix concurrent policy issue in unittest

    After merge of following commit: 4f17b8d837ebad4ef2e8ae5fe95ea968c7b8b587
    appears unstable error when we get denial from policy check.
    'Fix' mocks policy.check_policy method and tests that it was called.
    We do not test policy actions in related unittest suite located in
    'manila.tests.api.v1.test_share_networks' module, and should not.
