ALSA: caiaq: Don't abort when no input device is available

The previous fix to handle the error from setup_card() caused a
regression for the models that have no dedicated input device;
snd_usb_caiaq_input_init() just returns -EINVAL, and we treat it as a
fatal error although it should be ignored.

As a regression fix, change the error code to -ENODEV, and ignore this
error in the callee, to continue probing.
