SF: update scheduler's RefreshRateConfigs on hotplugs am: ac2bf48e

void SurfaceFlinger::initScheduler(const sp<DisplayDevice>& display) {

    if (mScheduler) {

        // In practice it's not allowed to hotplug in/out the primary display once it's been

        // connected during startup, but some tests do it, so just warn and return.

        ALOGW("Can't re-init scheduler");

        // If the scheduler is already initialized, this means that we received

        // a hotplug(connected) on the primary display. In that case we should

        // update the scheduler with the most recent display information.

        ALOGW("Scheduler already initialized, updating instead");

        mScheduler->setRefreshRateConfigs(display->holdRefreshRateConfigs());
