arch/xtensa/esp32[-|-s3]: Fix exception issue when pm active
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.
