Peter Zijlstra 8a070a5884 perf: Fix the nr_addr_filters fix
[ Upstream commit 388a1fb7da ]

Thomas reported that commit 652ffc2104 ("perf/core: Fix narrow
startup race when creating the perf nr_addr_filters sysfs file") made
the entire attribute group vanish, instead of only the nr_addr_filters
attribute.

Additionally a stray return.

Insufficient coffee was involved with both writing and merging the
patch.
