Jouni Malinen b9e8f920a8 tests: Split ap_vht160 into two test cases (ap_vht160 and ap_vht160b) 
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.
