cpuidle: mvebu: Fix the CPU PM notifier usage
As stated in kernel/cpu_pm.c, "Platform is responsible for ensuring that cpu_pm_enter is not called twice on the same CPU before cpu_pm_exit is called.". In the current code in case of failure when calling mvebu_v7_cpu_suspend, the function cpu_pm_exit() is never called whereas cpu_pm_enter() was called just before. This patch moves the cpu_pm_exit() in order to balance the cpu_pm_enter() calls.
