This translates to QDict in C. Since the QAPI schema language lacks the means to express 'object', we use 'any' instead. This is QObject in C. Commands taking a CpuModelInfo argument need to check the QObject is a QDict. For arm, riscv, and s390x, the code checks right before passing the QObject to visit_start_struct(). visit_start_struct() then checks again. Delete the first check. The error message for @props that are not an object changes slightly to the the message we get for this kind of type error in other contexts. Minor improvement. Additionally, error messages about members of @props now refer to 'props.prop-name' instead of just 'prop-name'. Another minor improvement. Both changes are visible in tests/qtest/arm-cpu-features.c.
