Subject: net: sched: change names of action number helpers to be aligned with
 the rest
Patch-mainline: v4.14-rc1
Git-commit: 3bcc0cec818fa969fe555b44443347211ed787a3
References: bsc#1056787

The rest of the helpers are named tcf_exts_*, so change the name of
the action number helpers to be aligned. While at it, change to inline
functions.
