tests: Skip ap_wpa2_tdls_concurrent_init on failure

A mac80211 TDLS validation change ended up breaking test functionality
that was needed for this test case. Instead of reporting this known
issue as a FAIL every time, mark the test as SKIP since the issues is
known and there are no plans of "fixing" it.
