Pavankumar Kondeti 632b40616e idle: add a check for need_resched() after rcu_idle_enter 
rcu_idle_enter() can wake up ksoftirqd to finish RCU callbacks
before entering idle. Hence add a check for need_resched() after
rcu_idle_enter(). The CPU enters idle without this check and
tasks queued on this CPU are starved until CPU exits idle.

The cpuidle subsystem has checks for need_resched() before
entering CPU idle, but these checks does not come into the
picture if cpuidle is not enabled or becomes active during
boot.
