[PATCH tip/core/rcu 01/41] rcu: Remove unused rcu_state externs

From: "Joel Fernandes (Google)" <joel@joelfernandes.org>

The rcu_bh_state and rcu_sched_state variables were removed during the
RCU flavor consolidations, but external declarations remain in tree.h.
This commit therefore removes these obsolete declarations.
