[PATCH net v2 0/2] net/smc: correct the reason code in smc_listen_find_device when fallback

[Guangguan Wang]

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.
