Remove all rcu head inits. We don't care about the RCU head state before passing it to call_rcu() anyway. Only leave the "on_stack" variants so debugobjects can keep track of objects on stack.

This assumption seems to be correct. I've already applied it to the maint branch and it must only be applied to the trunk.

v2: I've accidently send the version of maint instead the version for trunk. There were no real differences, but the paths.
