rcu: Remove redundant BH disabling in TINY_RCU
The TINY_RCU rcu_process_callbacks() function is only ever invoked from a softirq handler, which means that BH is already disabled. This commit therefore removes the redundant local_bh_disable() and local_bh_ennable() from this function. Signed-off-by: Paul E.
