Subject: net sched actions: Use proper root attribute table for actions
Patch-mainline: v4.14-rc1
Git-commit: df823b02970172f3e4003063699e333295b9b32d
References: bsc1056787

Bug fix for an issue which has been around for about a decade.
We got away with it because the enumeration was larger than needed.

Fixes: 7ba699c604ab ("[NET_SCHED]: Convert actions from rtnetlink to new netlink API")
