Lai Jiangshan 0cff810f54 rcu: Fix local_irq_disable() CONFIG_PROVE_RCU=y false positives
It is documented that local_irq_disable() also delimits RCU_SCHED
read-site critical sections.

See the document of synchronize_sched() or
Documentation/RCU/whatisRCU.txt.

So we have to test irqs_disabled() in rcu_read_lock_sched_held().
Otherwise rcu-lockdep brings incorrect complaint.
