Subject: [PATCH] cpuidle: Select a different state on tick_broadcast_enter()
 failures

If tick_broadcast_enter() fails in cpuidle_enter_state(),
try to find another idle state to enter instead of invoking
default_idle_call() immediately and returning -EBUSY which
should increase the chances of saving some energy in those
cases.
