kfdtest: Consolidate logic for ASSERT vs EXPECT

ASSERT failures result in immediate termination of the test. EXPECT
returns a failure but continues execution. Reserve ASSERT for required
functionality (node initialization, queue creation, etc) where the rest
of the test cannot run if that call fails. Use EXPECT everywhere else
