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.
