iio: chemical: sgp30: Handle IAQ thread creation failure

Browse Source 
kthread_run() can fail and return an error pointer, but sgp_probe() stores
it and returns success, so the device is registered without its IAQ thread
and sgp_remove() later passes the error pointer to kthread_stop(). Return
the error from probe instead.
