RDMA: Convert drivers using sizeof() to ib_respond_udata()

RDMA: Convert drivers using sizeof() to ib_respond_udata()

Convert the pattern:

    ib_copy_to_udata(udata, &resp, sizeof(resp));

Using Coccinelle:

@@
identifier resp;
expression udata;
@@

- ib_copy_to_udata(udata, &resp, sizeof(resp))
+ ib_respond_udata(udata, resp)

Run another pass with AI to propagate the return code correctly and
remove redundant prints.
