[PATCH 3/8] drm/exynos: fixed vflip, hflip case at the same time.

[Eunchul Kim]

This patch fixed vflip, hflip at the same time. If we want to change 180 degree about buffer,
then we can use h,vflip or 180 degree. we supports 180 degree using h,vflip.
but we make error handling in this case. so, fixed it.
