s390/cpumf: remove call to perf_event_update_userpage
The function cpumf_pmu_add and cpumf_pmu_del call function
perf_event_update_userpage(). This calls is obsolete, the calls add and
delete a counter event. Counter events do not sample data and the
event->rb member to access the sampling ring buffer is always NULL.
The function perf_event_update_userpage() simply returns in this case.
