perf/x86/intel: Fix build warning in intel_pmu_drain_pebs_nhm()

Browse Source 
Fengguang Wu reported this build warning:

    arch/x86/kernel/cpu/perf_event_intel_ds.c: In function 'intel_pmu_drain_pebs_nhm':
    arch/x86/kernel/cpu/perf_event_intel_ds.c:964:2: warning: format '%ld' expects argument of type 'long int', but argument 4 has type 'int'

Because pointer arithmetics result type is bitness dependent there's no natural
type to use here, cast it to long.
