s390/sclp: fix possible control register corruption
sclp_sync_wait() disables all external interrupt classes except for the service signal subclass. The static mask used for that however is wrong. It clears a couple of bits which shouldn't be cleared and on the other hand potentially does not clear bits which should be cleared. Fix this by using the same generic mask like we do it in our delay implementation.
