[PATCH] dhclient-script: fix bound

[Jonatan Schlag <jonatan.schlag@ipfire.org>]

[-- Attachment #1: Type: text/plain, Size: 1448 bytes --]

When we get a BOUND we should have only new_* variables set.
So it is stated in the manpage.
Apparently, also old_* variables are set so we never got into the block where the IP address was set.
We now always set a new IP Address when we get a BOUND.

Fixes: #11363
