ALSA: 6fire: Fix leftover global pointers after probe failures

snd-usb-6fire driver holds devices[] and chips[] pointer arrays to
keep the usb_device and sfire_chip objects assigned to multiple
interfaces.  Those are, however, not properly cleared at the error
path of usb6fire_chip_probe(), which may confuse the later probes.
Also, the use of two pointer arrays makes things complicated; chips[]
may be NULL while devices[] may be left over.

For addressing this inconsistency, unify the pointer arrays, and use
only chips[] for managing the multiple devices, while the device is
checked with chip->dev pointer, instead.  Also, the assignment of
chips[] is moved at a later point where the probe successfully
returns, so that we don't leave the pointer there after the error.
