In case we have already established connection to nvmf target, it shouldn't be allowed to change the model_number. E.g. if someone will identify ctrl and get model_number of "my_model" later on will change the model_numbel via configfs to "my_new_model" this will break the NVMe specification for "Get Log Page – Persistent Event Log" that refers to Model Number as: "This field contains the same value as reported in the Model Number field of the Identify Controller data structure, bytes 63:24." Although it doesn't mentioned explicitly that this field can't be changed, we can assume it. So allow setting this field only once: using configfs or in the first identify ctrl operation.
