rcu: Account for rcu_all_qs() in cond_resched()

Browse source

If cond_resched() returns false, then it has already invoked
rcu_all_qs().  This is also invoked (now redundantly) by
rcu_note_voluntary_context_switch().  This commit therefore changes
cond_resched_rcu_qs() to invoke rcu_note_voluntary_context_switch_lite()
instead of rcu_note_voluntary_context_switch() to avoid the redundant
invocation of rcu_all_qs().
