mm-video-v4l2: vdec: fix invalid stride and scanlines issue

Update only frame width and height and not stride and scanlines
in FBD as we don't get stride and scanlines from the driver,
otherwise, invalid stride and scanlines are received by the
client when crop parameters change event is detected in FBD.
