habanalabs: refactor fence handling in hl_cs_poll_fences
To avoid checking if fence exists multipled times, changed fence handling to depend only on the fence status field: Busy, which means CS still did not completed : Add its QID so multi CS wait on its completion. Finished, which means CS completed and fence exists: Raise its completion bit if it finished mcs handling and update if necessary the earliest timestamp. Gone, which means CS already completed and fence deleted: Update multi CS data to ignore timestamp and raise its completion bit.
