[S390] cio: Disable channel path measurements on shutdown/reboot.

Browse source

Make sure channel path measurements are disabled via a reboot notifier
since we cannot rely on userspace to disable it again after enabling
it. This is 1. clean and 2. makes sure that channel path measurements
do not stay enabled after a reboot not involving a subsystem reset
(which would lead to the channel subsystem scribbling onto random
memory).
