s390/cpum_cf: Deny all sampling events by counter PMU
Deny all sampling event by the CPUMF counter facility device driver and return -ENOENT. This return value is used to try other PMUs. Up to now events for type PERF_TYPE_HARDWARE were not tested for sampling and returned later on -EOPNOTSUPP. This ends the search for alternative PMUs. Change that behavior and try other PMUs instead.
