Adding on, once you have the multiversion kernels set up, select 2) Advanced
options at boot and then select the desired kernel.
Removing the new one will make the old one the default.

If your server is up, back out can be done easily
First make sure /etc/zypp/zypp.conf has
multiversion = provides:multiversion(kernel)
multiversion.kernels = latest,latest-1,running
Then simply install the old one
zypper install kernel-default-4.4.126-94.22.1.s390x --oldpackage
And remove the new one
zypper remove kernel-default-4.4.131-94.29-default
That should do it.
Reboot
