Description:
If you have 2 mgmds in the cluster and check the ndb_mgm both entries for the mgm-nodes show the same IP even if the mgmds are on different hosts.

How to repeat:
setup a cluster with 2 mgmds on different hosts and check output of SHOW in ndb_mgm.

Suggested fix:
show the IP of the mgmd-hosts.

I checked this with the latest 5.1 clone. The really weird item here, is that I edit the config.ini as follows:

[ndb_mgmd]
Id: 1
HostName: ndb08

[ndb_mgmd]
Id: 19
HostName: ##.###.1.94 (# = numbers removed for security reasons)

The ##.###.1.94 = ndb09 and ndb08 = ##.###.1.93

I only started a ndb_mgmd on ndb08, and if you do a show you get:

[ndb_mgmd(MGM)] 2 node(s)
id=1    @##.###.1.94  (Version: 5.1.0)
id=19 (not connected, accepting connect from ##.###.1.94)

The managment server shows to be running on ##.###.1.94 but it really is running on ##.###.1.93.

Unless this actually stops things working (e.g. unable to start the mgmd), i'll lower the severity and priority of this bug.
