[PATCH] drm/exynos: fix not to remain exynos_gem_obj as a leak

[Seung-Woo Kim]

From: YoungJun Cho <yj44....@samsung.com>

The exynos_drm_gem_create() only calls drm_gem_object_release()
when exynos_drm_alloc_buf() is failed, and exynos_gem_obj remains
as a leak, which is allocated in exynos_drm_gem_init().
So this patch fixes it not to remain as a leak.
