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.
