Subject: [PATCH] perf/core: make nr_addr_filters attribute static

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

kernel/events/core.c:12170:1: warning: symbol 'dev_attr_nr_addr_filters' was not declared. Should it be static?

Fixes: 6e855cd4f4b52 ("perf/core: Let userspace know if the PMU supports address filters")
