When a new mode is applied, the current frame rate is reset to the mode's default one. In order to correctly report the currently configured vertical blanking for s_frame_interval users, verify that the desired frame rate has not been changed. If that's the case, compute the correct blanking value and reflect it through the corresponding v4l2 control.
