CameraITS: fix data copy array out of bound issue

We assumed that the Y stride was always larger or equal to chroma
stride for YUV. This isn't a reasonable assumption as the chroma
stride could be larger for interleaved UV format. This change
uses the max row stride across all planes as the intermediate
array size.
