snd_es1688_free() will call snd_es1688_init() which in turn use the
uninitialized spin locks and other data. So I end up with the below
patch. snd_device_new() could also return errors and will be handled
in the same way.
I don't have the hardware, however tests show it at least fixed the
boot time irq mismatch warnings.
Daniel, thanks for your initial implementation and please kindly
confirm the below 3rd version :)
Thanks,
Fengguang
