cpuidle: fix fallback mechanism for suspend to idle in absence of enter_freeze
Commit 51164251f5c3 "sched / idle: Drop default_idle_call() fallback from call_cpuidle()" made find_deepest_state() return non-negative value and check all the states with index > 0. Also as a result, find_deepest_state() returns 0 even when enter_freeze callbacks are not implemented and enter_freeze_proper() is called which ends up crashing the kernel. This patch updates the check for index > 0 in cpuidle_enter_freeze and cpuidle_idle_call(when idle_should_freeze is true) to restore the suspend-to-idle functionality in absence of enter_freeze callback.
