Description

I create nodemap1 and add range then delete the range in anthoer nodemap2.
Then nodemap1 ip range disappeared.

[Test steps:]
lctl nodemap_add nodemap1
lctl nodemap_add nodemap2
lctl nodemap_add_range --name nodemap1 --range 192.168.19.[0-255]@o2ib20
lctl get_param nodemap.nodemap1.* | grep start_nid
lctl nodemap_del_range --name nodemap2 --range 192.168.19.[0-255]@o2ib20
lctl get_param nodemap.nodemap1.* | grep start_nid

[Test result:]
[root@mdsb1 ~]# lctl nodemap_add nodemap1
[root@mdsb1 ~]# lctl nodemap_add nodemap2
[root@mdsb1 ~]# lctl nodemap_add_range --name nodemap1 --range 192.168.19.[0-255]@o2ib20
[root@mdsb1 ~]# lctl get_param nodemap.nodemap1.* | grep start_nid

{ id: 20, start_nid: 192.168.19.0@o2ib20, end_nid: 192.168.19.255@o2ib20 }

[root@mdsb1 ~]# lctl nodemap_del_range --name nodemap2 --range 192.168.19.[0-255]@o2ib20
[root@mdsb1 ~]# lctl get_param nodemap.nodemap1.* | grep start_nid
