rcu: Replace the rcu_barrier enum with pointer to call_rcu*() function
The rcu_barrier enum causes several problems:
(1) you have to define the enum somewhere, and there is no
convenient place,
(2) the difference between TREE_RCU and TREE_PREEMPT_RCU causes
problems when you need to map from rcu_barrier enum to struct
rcu_state,
(3) the switch statement are large, and
(4) TINY_RCU really needs a different rcu_barrier() than do the
treercu implementations.
So replace it with a functionally equivalent but cleaner function
pointer abstraction.
