CHROMIUM: drm/exynos: prime: Fix exynos_drm_gem_dmabuf_mmap

Exynos stores a pointer to an exynos_drm_gem_obj in dma_buf->priv, not
a pointer to its base drm_gem_object field.

While we are at it, fix up the functions name and some space/tab issues.

BUG=none
TEST=Compile test; As far as I can tell, this function isn't actually used
