[gstreamer-vaapi][encode][Jpeg] jpeg file show noise by using UYVY input format.

[feiwan1]

When using UYVY format as the input for jpeg encode, the output file show noise.
(This need the patch #615 )

cmdline:
$ gst-launch-1.0 videotestsrc num-buffers=1 ! video/x-raw,format=UYVY ! vaapijpegenc ! jpegparse ! filesink location=out.uyvy.jpeg

And I used jpegenc from libva-utils got the same result:
$ jpegenc 320 240 in.uyvy out.jpeg 2 50

Ps, when using YUY2, the output looks good.

@feiwan1 I tried your command with #615 but no this issue on KBL. What platform do you run it on? My tried commit is 54a198d. Thanks.

I tried the command with #615 in EHL Simics, can see this issue.
it fails with UYVY, but looks good when tried with YUY2.

@feiwan1 Could you please try #648 ? Thanks.
