Fix exception issue when PM and DEBUG_ASSERTIONS enabled for esp32 and esp32s3. This error happens due to PM system workflow, when system gets into sleep-modes with removing PM_NORMAL count, system is raising an exception for not having enough number of PM_NORMAL state count if DEBUG_ASSERTIONS enabled.
