firewire: core: optimize card shutdown
This fixes a regression by "firewire: keep highlevel drivers attached during brief connection loss": There were 2 seconds unnecessary waiting added to the shutdown procedure of each controller. We use card->link as status flag to signal the device handler that there is no use to wait for a come-back. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
