[patch] ALSA: hda ca0132 - remove unused error handling code

[Dan Carpenter <dan.carpenter@oracle.com>]

We never save the return value from chipio_write() so "err" is always
zero here, not less than zero.

The other option would be to save the return value.  I don't have the
hardware and I worried that there was a reason we don't save it.  The
current code is misleading because it looks like it's checked until
you notice that the "err = " bit is missing.
