media: ov5640: Drop dead code using frame_interval
The ov5640_update_pixel_rate() function handles the parallel and MIPI
CSI-2 cases separately.
When running on a parallel setup the V4L2_CID_PIXEL_RATE value is
calculated at the beginning of the function using the values configured
with the frame_interval operations, and then the function immediately
returns.
The remaining of the function handles the MIPI CSI-2 configuration and
should not use the 'current_fr' and 'def_fps' fields as those are only
relevant for parallel mode.
Drop a small section of dead code that updates vblank using
frame_interval on a MIPI CSI-2 setup.
