RDMA/nldev: Add support to dump device type and parent device if exists

Browse Source 
If a device has a specific type or a parent device, dump them as well.

Example:
$ rdma dev show smi1
3: smi1: node_type ca fw 20.38.1002 node_guid 9803:9b03:009f:d5ef sys_image_guid 9803:9b03:009f:d5ee type smi parent ibp8s0f1
