Subject: ALSA: 6fire: Fix probe of multiple cards
commit 9b389a8a022110b4bc055a19b888283544d9eba6 upstream.
The probe code of snd-usb-6fire driver overrides the devices[] pointer
wrongly without checking whether it's already occupied or not. This
would screw up the device disconnection later.
Spotted by coverity CID 141423.
