RDMA/cma: Add RDMA_CM_EVENT_ADDR_CHANGE event
Add an RDMA_CM_EVENT_ADDR_CHANGE event can be used by rdma-cm
consumers that wish to have their RDMA sessions always use the same
links (eg <hca/port>) as the IP stack does. In the current code, this
does not happen when bonding is used and fail-over happened but the IB
link used by an already existing session is operating fine.
Use the netevent notification for sensing that a change has happened
in the IP stack, then scan the rdma-cm ID list to see if there is an
ID that is "misaligned" with respect to the IP stack, and deliver
RDMA_CM_EVENT_ADDR_CHANGE for this ID. The consumer can act on the
event or just ignore it.
