chore(runtime): fix logging of RMI and RSI commands

This patch fixes the following issues with logging:
- logging of RMI function name in rmi_log_on_exit()
INFO("SMC_RMI_%-25s", handler->fn_name);
now matches the maximum name length of RSI handler
function SMC_RSI_RDEV_GET_INTERFACE_REPORT of 33 chars
excluding the null terminator.
- removed logging of return status and results of RSI
calls which return to host, because these values are
valid only when after the call execution continues in
realm.
