firewire: cdev: always wait for outbound transactions to complete

We must not use fw_cancel_transaction() because it cannot correctly
abort still-active transactions.  The only place in core-cdev where this
matters is when the file is released.  Instead of trying to abort the
transactions, we wait for them to complete normally, i.e., until all
outbound transaction resources have been removed from the IDR tree.
