change the dump dir format to be more readable

Browse Source 
Resolves: bz880551

Currently on fedora directory name of kdump is like 14.11.12-03:40:30.
It's not as readable as RHEL6. The old format of dir is host_ip-date-time.
This patch changes it back like ole one as below.
192.168.122.234-2012-10-31-05:17:20

If can't get HOST_IP for a network kudmp, we just fail. Becasue most
likely any attempt to save dump will also fail.
