Ivan Grokhotkov 0716e65955 pm: prevent entering light sleep again immediately after wakeup ...

When light sleep is finished on one CPU, it is possible that the other
CPU will enter light sleep again very soon, before interrupts on the
first CPU get a chance to run. To avoid such situation, set a flag
for the other CPU to skip light sleep attempt.
