The C++ API already provides access to the model of the connected device
in NitrokeyManager::get_connected_device_model(). This patch also
exposes this information in the C API by adding NK_get_device_model. As
there might be no device connected, the function returns a boolean
indicating the connection status and writes the model of the connected
device to a pointer passed as an argument.
These were to meant, that the sizes were confirmed for Pro and not for Storage, during library development. Storage has maintained the compatibility, hence there is no need for the mentioned marks.
