The function smc_find_ism_store_rc is not only used for ism, so it is reasonable to change the function name to smc_find_device_store_rc. The ini->rc is used to store the last error happened when finding usable ism or rdma device in smc_listen_find_device, and is set by calling smc_ find_device_store_rc. Once the ini->rc is assigned to an none-zero value, the value can not be overwritten anymore. So the ini-rc should be set to the error reason only when an error actually occurs. When finding ISM/RDMA devices, device not found is not a real error, as not all machine have ISM/RDMA devices. Failures after device found, when initializing device or when initializing connection, is real errors, and should be store in ini->rc. SMC_CLC_DECL_DIFFPREFIX also is not a real error, as for SMC-RV2, it is not require same prefix.
