Guoqing Jiang	d3a95ccaaf	block/rnbd: call kobject_put in the failure path ... Per the comment of kobject_init_and_add, we need to cleanup the memory by call kobject_put. Also we need to call kobject_del for the other failure cases if the kobject_init_and_add doesn't fail.

Lutz Pogrell	786998050c	block/rnbd-srv: close a mapped device from server side. ... The forceful close of an exported device is required for the use case, when the client side hangs, is crashed, or is not accessible. There have been cases observed, where only some of the devices are to be cleaned up, but the session shall remain. When the device is to be exported to a different client host, server side cleanup is required.
