4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jiri Pirko <jiri@xxxxxxxxxxxx>
[ Upstream commit b59e6979a86384e68b0ab6ffeab11f0034fba82d ]
Move static key increments to the beginning of the init function
so they pair 1:1 with decrements in ingress/clsact_destroy,
which is called in case ingress/clsact_init fails.
Fixes: 6529eaba33f0 ("net: sched: introduce tcf block infractructure")
