gpio: cdev: fix missed label sanitizing in debounce_setup()
When adding sanitization of the label, the path through
edge_detector_setup() that leads to debounce_setup() was overlooked.
A request taking this path does not allocate a new label and the
request label is freed twice when the request is released, resulting
in memory corruption.
Add label sanitization to debounce_setup().
