ALSA: 6fire: Fix probe of multiple cards
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. Cc: <stable@vger.kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
