[Guoqing Jiang <guoqing.jiang@linux.dev>]

Hi,

Several issues appeared if we rmmod siw module after failed to insert
the module (with manual change like below).

        if (rv)
                goto out_error;

+       goto out_error;
        rdma_link_register(&siw_link_ops);

Basically, these issues are double free, use before initalization or
null pointer dereference. For more details, pls review the individual
patch.

Thanks,
Guoqing
