net/smc: code cleanup smc_listen_work
In smc_listen_work() the variables rc and reason_code are defined which
have the same meaning. Eliminate reason_code in favor of the shorter
name rc. No functional changes.
Rename the functions smc_check_ism() and smc_check_rdma() into
smc_find_ism_device() and smc_find_rdma_device() to make there purpose
more clear. No functional changes.
