When a remote dump target is specified, kdump dracut module prefixes
'kdump-' to network interface name (ifname) as kernel assigned names
are not persistent. In fadump mode, kdump dracut module is added to
the default initrd, which adds the 'kdump-' prefix to the ifname of
the prodcution kernel itself. If fadump mode is disabled after this,
kdump dracut module picks the ifname that is already prefixed with
'kdump-' in the production kernel and adds another 'kdump-' to it,
making the ifname something like kdump-kdump-eth0 for kdump kernel.
Eventually, kdump kernel fails with below traces:
dracut-initqueue[246]: RTNETLINK answers: Network is unreachable
dracut-initqueue[246]: arping: Device kdump-kdump-eth0 not available.
The ip command shows the below:
kdump:/# ip addr show kdump-kdump-eth0
2: kdump-kdump-eth: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 \

kdump:/#
The trailing 0 from kdump-kdump-eth0 is missing in the ifname, probably
truncated owing to ifname length limit, while setting.
This patch fixes this by avoiding addition of the prefix 'kdump-' when
such prefix is already present in the ifname.
