jpegdec: Pull row_stride from GST_VIDEO_FRAME_PLANE_STRIDE()

Browse source 
The libjpeg-turbo internal state might not be correctly initialized for
the first frame in a stream, pull the frame stride from gstreamer frame
metadata instead, which is correct even for the first frame, and which
makes this code consistent with the surrounding lines.
