disp: msm: dsi: skip clearing dynamic refresh done status in dsi ctrl ISR

After triggering dynamic refresh, if there is any dsi_ctrl_isr, dynamic
refresh done status also gets cleared as part of it. Because of this,
wait4dynamic_refresh_done timeout error is seen even though dynamic
refresh is done successfully.
