msm: mdss: send idle_time notification only if positive



User-land program can configure idle_time as zero when they want to
disable idle_time notifications. In the current implementation, driver
does not modify current idle timer if idle_time is zero but it may still
send the notification if the previous timer expires. Prevent this
notification if idle_time is set as zero.
