You can find the pre-removal script here:

/var/lib/dpkg/info/open-iscsi.prerm

I would comment out all commands or simply insert

exit

as the second line of this script. This should allow you to complete the
removal. Afterwards it is maybe advisable to reboot just to make sure
that your system is in a clean state again.

Then it should be possible to install the newest version of open-iscsi
(2.0.730-1) which has a fix for this bug:
