Do not try to dereference dpi if it is NULL.
Since dpi can never be NULL when mtk_dpi_set_display_mode() is called,
remove the message.

The drm_gem_object_lookup() function prototype changed while this
driver was added, so it fails to build now:

drivers/gpu/drm/mediatek/mtk_drm_gem.c: In function 'mtk_drm_gem_dumb_map_offset':
drivers/gpu/drm/mediatek/mtk_drm_gem.c:142:30: error: passing argument 1 of 'drm_gem_object_lookup' from incompatible pointer type [-Werror=incompatible-pointer-types]
  obj = drm_gem_object_lookup(dev, file_priv, handle);

This fixes the new caller as well.

It's unused, and really this helper should only look at the state
structure and nothing else.

v2: Fix commit message (Laurent).

v3: Rebase onto mtk driver merge.

v3: Drop unrelated hunk, spotted by Laurent.
