Ma Ke d64fc94f7b drm/client: fix null pointer dereference in drm_client_modeset_probe 
commit 113fd6372a5bb3689aba8ef5b8a265ed1529a78f 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.

Fixes: cf13909aee ("drm/fb-helper: Move out modeset config code")
