v4l2: fix error in calculating padding bottom for tile format
requested to merge elliot_chen/gstreamer:v4l2-fix-error-in-calculating-padding-bottom-for-tile-format into main
- For output tile format, "padded_height" is divided by the "tile_height" in alignment calculation. While "padded_height" is not multiplied by "tile_height" after it. It will cause error in the calculation of the "padding_bottom".
- As the result, The "padding_bottom" alignment value in video meta of the out video buffers are all incorrect if the output format is tile format.
