Each lockless action currently does its own RCU locking in ->act().
This is allows using plain RCU accessor, even if the context

This change drops the per action RCU lock, replace the accessors
with _bh variant, cleans up a bit the surronding code and documents
the RCU status in the relevant header.
No functional nor performance change is intended.
The goal of this patch is clarifying that the RCU critical section
used by the tc actions extends up to the classifier's caller.
This and 2/5 seems to stand on their own merit.
