Ma Ke 5291d4f734 drm/client: fix null pointer dereference in drm_client_modeset_probe ...

commit 113fd6372a upstream.

In drm_client_modeset_probe(), the return value of drm_mode_duplicate() is
assigned to modeset->mode, which will lead to a possible NULL pointer
dereference on failure of drm_mode_duplicate(). Add a check to avoid npd.
