backlight: qcom-wled: Fix NULL pointer dereference in wled_remove()

Browse Source 
wled_probe() doesn't set the driver data for the platform device.
As a result, platform_get_drvdata() in wled_remove() will return NULL,
and the first dereference of it crashes on unbind.

Set the platform device driver data in wled_probe().
