Subject: [PATCH net-next] smc: rename smc_find_ism_store_rc to reflect broader usage

The function smc_find_ism_store_rc() is used to record the reason
why a suitable device (either ISM or RDMA) could not be found.
However, its name suggests it is ISM-specific, which is misleading.

Rename it to better reflect its actual usage.

No functional changes.
