Solution
Downgrade libnl packages and wait for an upgrade of network-manager package
Step 1
Try to downgrade libnl with apt-get as in @Max answer:
sudo apt-get install libnl-3-200=3.2.21-1 libnl-route-3-200=3.2.21-1 libnl-genl-3-200=3.2.21-1
Step 2
If Step 1 fails,
because the packages aren't anymore in your cache and obviously cannot be downloaded by package manager, you need to downgrade libnl packages manually (download + install):
Download and copy them to your system
[ from booting a live distrib/rescue cd or from another computer + usb stick ]
Download links for amd64: libnl libnl-genl libnl-route
Download links for i386: libnl libnl-genl libnl-route
Back to your system, where you saved these .deb files, install them with dpkg:
sudo dpkg -i libnl-*.deb
Step 3
Now you should be able to (re)start NetworkManager and bring back networking:
sudo service network-manager restart
