sporadic failure while testing share server create command

[Archana Kumari]

Here, the test ("test_list_shares_by_status") is only supposed to worry about the shares it creates
but instead, it lists all the shares matching the status and then tries to go through each share and verify if the status is as it was filtered.

The test error: https://zuul.opendev.org/t/openstack/build/6d753626ab3d4e7b993404c1f138112c
