disp: msm: dp: send hpd notification before updating mst_active
When processing mst hpd low, the driver is clearing mst_active before triggering hpd notification. The hpd notifier is common for both sst and mst and since mst_active is cleared it incorrectly treats this as sst unplug. This change switches the order of these operations to trigger hpd notification before clearing mst_active.
