ALSA: 6fire: Fix probe of multiple cards

Browse Source 
commit 9b389a8a02 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.
