[NetLabel]: correct usage of RCU locking
This fixes some awkward, and perhaps even problematic, RCU lock usage in the
NetLabel code as well as some other related trivial cleanups found when
looking through the RCU locking. Most of the changes involve removing the
redundant RCU read locks wrapping spinlocks in the case of a RCU writer.
