During hibernation or restoration, freeze_secondary_cpus checks num_online_cpus via BUG_ON, and the subsequent save_processor_state also does the checking with WARN_ON. In the case of CONFIG_PM_SLEEP_SMP=n, freeze_secondary_cpus is not defined, but the sole possible condition to disable CONFIG_PM_SLEEP_SMP is !SMP where num_online_cpus is always 1. We also don't have to check it in save_processor_state. So remove the unnecessary checking in save_processor_state.
