[net,v2,0/3] net/sched: fix action bind logic

Message

Some actions are not handling the case where an action can be created and bound to a
filter independently. These actions are checking for parameters only passed
in the netlink message for create/change/replace, which then errors out
for valid uses like:
tc filter ... action pedit index 1

In the iproute2 side, we saw a couple of actions with their parsers
broken when passing "index 1" as the only action argument, while the kernel
side accepted it correctly. We fixed those as well.

v1->v2:
- Missed clean up pointed out by Simon
