rcu/kvfree: Adjust names passed into trace functions
Currently trace functions are supplied with "rcu_state.name"
member which is located in the structure. The problem is that
the "rcu_state" structure variable is local and can not be
accessed from another place.
To address this, this preparation patch passes "slab" string
as a first argument.
