gpio: sim: check the label length when setting up device properties
If the user-space sets the chip label to an empty string - we should check the length and not override the default name or else line hogs will not be properly attached. Fixes: cb8c474e79be ("gpio: sim: new testing module") Signed-off-by: Bartosz Golaszewski <brgl@bgdev.pl>
