disp: msm: dsi: force VRR on RFI default value setting

Browse Source 
Currently on video mode panel, when the RFI bit clock
rate is set back to the default rate, the driver is not
detecting that a VRR operation is necessary due to
unchanged porches value.

This change is forcing a VRR update on video mode panel
whenever the RFI bit clock rate is changed.
