RDMA/nldev: provide detailed CM_ID information
Implement RDMA nldev netlink interface to get detailed CM_ID information. Because cm_id's are attached to rdma devices in various work queue contexts, the pid and task information at restrak_add() time is sometimes not useful. For example, an nvme/f host connection cm_id ends up being bound to a device in a work queue context and the resulting pid at attach time no longer exists after connection setup. So instead we mark all cm_id's created via the rdma_ucm as "user", and all others as "kernel". This required tweaking the restrack code a little. It also required wrapping some rdma_cm functions to allow passing the module name string.
