[PATCH 4/4] xtensa: hibernate: remove WARN_ON in save_processor_state

[Song Shuai]

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.

So remove the unnecessary checking in save_processor_state.
