net/sched: act_api: unexport tcf_action_dump_1()

This isn't used outside act_api.c, but is called by tcf_dump_walker()
prior to its definition. So move it upwards and make it static.

Simultaneously, reorder the variable declarations so that they follow
the networking "reverse Christmas tree" coding style.
