[LU-12778] sanity-sec test 12 fails with 'nodemap_add failed with 1'

Description

sanity-sec test_12 fails with 'nodemap_add failed with 1' and then test_13, test_14 and test_15 all fail because a nodemap with the same name as the one they are creating exists. Many of these failures were previously attributed to LU-12428, but the patches for that ticket have landed. Thus, I’m opening a new ticket for these failures.

Looking at the suite_log at https://testing.whamcloud.com/test_sets/04c45a6c-d6fe-11e9-9fc9-52540065bddc we see

Another example, not sanity-sec test 12, but 9
