[PATCH] mjpeg: Don't warn when on unsupported image formats

[Christophe Fergeau <cfergeau@xxxxxxxxxx>]

When trying to start mjpeg compression mode, mjpeg_encoder_start_frame()
tests the image format as its only able to compress 24/32bpp images. On
images with lower bit depths, we return MJPEG_ENCODER_FRAME_UNSUPPORTED to
indicate this is not a format we can compress. However, this return goes
with a spice_warning("unsupported format"). As the rest of the code can
cope with this unsupported format by not doing mjpeg compression, it's
nicer to downgrade this spice_warning() to spice_debug().
