Heiko Carstens 0b991f5cdc s390/cachinfo: add missing facility check to init_cache_level() 
Stephen Powell reported the following crash on a z890 machine:

The illegal operation was executed because of a missing facility check,
which should have made sure that the ECAG execution would only be executed
on machines which have the general-instructions-extension facility
installed.
