From: Jamal Hadi Salim <jhs@mojatatu.com>

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

Thanks to Jiri Pirko for spotting it.
