ceph: fix intermittent volume unit test

The unit test TestConfigureCVDevices was failing intermittently
due to comparing the first element of the slice of two elements.
The slice ordering is not guaranteed, which caused a failure
intermittently. The test only compares the critical values in the test
and no need to check elements of the slice.
