RDMA/core: Add an rb_tree that stores cm_ids sorted by ifindex and remote IP
Add to the cma, a tree that keeps track of all rdma_id_private channels
that were created while in RoCE mode.
The IDs are sorted first according to their netdevice ifindex then their
destination IP. And for IDs with matching IP they would be at the same node
in the tree, since the tree data is a list of all ids with matching destination IP.
The tree allows fast and efficient lookup of ids using an ifindex and
IP address which is useful for identifying relevant net_events promptly.
