Subject: [PATCH 1/3] perf: arm-ni: Remove spurious NULL in attribute_group
 definition

This NULL value is most-likely a copy-paste error from an array
definition. So far the NULL didn't have any effect.
As there will be a union in struct attribute_group at this location,
it will trigger a compiler warning.
