Currently two different XDP programs share a static variable for different purposes (picking where to redirect on shared umem test & whether to drop a packet). This can be a problem when running full test suite - idx can be written by shared umem test and this value can cause a false behavior within XDP drop half test. Introduce a dedicated variable for drop half test so that these two don't step on each other toes. There is no real need for using __sync_fetch_and_add here as XSK tests are executed on single CPU.
