[PATCH] iio: proximity: hx9023s: Fix error code in hx9023s_property_get()

[Dan Carpenter]

If we're returning because "reg >= HX9023S_CH_NUM" then set the error code
to -ENIVAL instead of success.

Fixes: 60df548277b7 ("iio: proximity: Add driver support for TYHX's HX9023S capacitive proximity sensor")
