IB/core: Fix a potential array overrun in CMA and SA agent

Orabug: 26124118

Fix array overrun when going over callback table.
In declaration of callback table, the max size isn't provided and in
registration phase, it is provided.

There is potential scenario where a new operation is added and it is not
supported by current client. The acceptance of such operation by ib_netlink
will cause to array overrun.

Fixes: 809d5fc9bf65 ("infiniband: pass rdma_cm module to
netlink_dump_start")
Fixes: b493d91d333e ("iwcm: common code for port mapper")
Fixes: 2ca546b92a02 ("IB/sa: Route SA pathrecord query through netlink")
