Baskov Evgeniy 0862d95b43 media: s5p-jpeg: handle error condition in s5p_jpeg_probe 
If an error happens in jpeg_get_drv_data(), i.e. match fails,
jpeg->variant field is NULL, so we cannot access it.

Consider device probe failed if jpeg->variant is NULL.

Found by Linux Driver Verification project (linuxtesting.org).
