[master] pep8 jobs TIMING OUT randomly

[yatin]

After https://review.opendev.org/c/openstack/neutron/+/806246 patch pep8 job is taking more than 30 minutes and TIMES_OUT. Specifically flake8 is taking much time now. Before the patch approx 2 minutes and now more than 12 minutes.

    Fix pep8 endless loop in "test_update_flows_for_vlan_remote_group"

    To be honest, I don't know the reason why pep8 was stopped when
    checking "test_update_flows_for_vlan_remote_group". This patch
    indents the "mock.call" list and creates a variable, instead
    of passing the list inside the assert method.

    I've manually tested the pep8 job. In my development environment
    not takes 43 seconds, instead of 14 minutes.
