Turn comparison call into assertion in test_usm_ndarray_ctor::test_flags

[oleksandr-pavlyk]

Moved the assertion about comparison with generic types before other assertions in test_flags test

This change is made in reference to Coverity scan issue, which is a false positive, but the test can be improved anyway.
