firewire: cdev: remove unneeded idr_find() from complete_transaction()
Outbound transactions are never aborted with release_client_resource(), so it is not necessary for complete_transaction() to check whether the resource is still registered. Only shutdown_resource() can abort such an transaction, and this is already handled with the in_shutdown check.
