msm_fb: Avoid backlight scaling during resume until backlight is set

Currently, if we try to perform backlight scaling before we set the
backlight on the target during resume, display doesn't come up
due to backlight level zero set on target. Hence, avoid backlight
scaling until backlight is set on the target during resume.
