habanalabs: fix NULL pointer dereference
When polling fences for multi CS, it is possible that fence is
no longer exists (its corresponding CS completed and the fence was
deleted) but we still accessing its parameters, causing NULL pointer

Fixed by checking if fence exits before accessing its parameters.
