Subject: [PATCH] BUG: Fix test_impossible_feature_enable failing without
 BASELINE_FEAT

If the build has no baseline features set, the test ended up setting
e.g. NPY_ENABLE_CPU_FEATURES="ASIMDHP, None". This actually made the
execution succeed, as the warning for decoding "None" overrode the
error for the real feature. Fix the error handling there by removing
the errorneous "return 0;", add a test for this, and avoid passing
"None" by accident.
