tests: Allow local disconnect in openssl_cipher_suite_config_wpas

The openssl_ciphers="EXPORT" case may result in locally generated
disconnection event if the OpenSSL version used in the build rejects
export ciphers in default configuration (which is what OpenSSL 1.1.0
will likely do). Don't report a test case failure in such a case.
