Heiko Carstens 77bb36e57b s390/cacheinfo: add missing facility check ...

Git commit d97d929f06 ("s390: move cacheinfo sysfs to generic cacheinfo
infrastructure") removed the general-instructions-extension availability
check before the ecag instruction is executed.
Without this check this may lead to crashes on machines without this facility.
Therefore add the check again where needed.
