These VHT160 with DFS cases were in a single test case to optimize test execution time with parallel wait for the 60 second CAC. However, this design has become difficult to support with the kernel changes that allow radar events to be shared between interfaces. To avoid need for more workarounds here just for testing purposes, split this into two test cases so that conflicting events from another interface do not cause the test case to fail.
