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.
