i2o_cfg_passthru cleanup

This patch fixes a number of issues in i2o_cfg_passthru{,32}:
- i2o_msg_get_wait() return vaile is not checked;
- i2o_message memory leaks on error paths;
- infinite loop to sg_list_cleanup in passthru32

It's important issue because of i2o_cfg_passthru is used by raidutils for
monitorig controllers state, and in case of memory shortage it leads to the
node crash or disk IO stall.
