[PATCH] perf/core: make nr_addr_filters static

[PATCH] perf/core: make nr_addr_filters static

[Ben Dooks]

The dev_attr_nr_addr_filters is not accessed outside of kernel/events/core.c
so make it static to avoid the following sparse warning:

kernel/events/core.c:11288:1: warning: symbol 'dev_attr_nr_addr_filters' was not declared. Should it be static?
