[PATCH tip/core/rcu 13/12] Remove wrapper definitions for obsolete RCU update functions

[Paul E. McKenney]

None of synchronize_rcu_bh, synchronize_rcu_bh_expedited, call_rcu_bh,
rcu_barrier_bh, synchronize_sched, synchronize_sched_expedited,
call_rcu_sched, rcu_barrier_sched, get_state_synchronize_sched, and
cond_synchronize_sched are actually used.  This commit therefore removes
their trivial wrapper-function definitions.

[ paulmck: The intent was to defer this to the following release, but
  there are no more uses of these functions, so full speed ahead!!! ]
