Subject: [PATCH -next] perf/core: make two symbols static

Fix sparse warnings:

kernel/events/core.c:6278:6: warning: symbol 'perf_pmu_snapshot_aux' was not declared. Should it be static?
kernel/events/core.c:10118:1: warning: symbol 'dev_attr_nr_addr_filters' was not declared. Should it be static?
