The kublk mock ublk server allows multiple data copy mode arguments to be passed on the command line (--zero_copy, --get_data, and --auto_zc). The ublk device will be created with all the requested feature flags, however kublk will only use one of the modes to interact with request data (arbitrarily preferring auto_zc over zero_copy over get_data). To clarify the intent of the test, don't allow multiple data copy modes to be specified. --zero_copy and --auto_zc are allowed together for --auto_zc_fallback, which uses both copy modes. Don't set UBLK_F_USER_COPY for zero_copy, as it's a separate feature. Fix the test cases in test_stress_05 passing --get_data along with --zero_copy or --auto_zc.
