drm/rockchip: dsi: ignore return value of drm_panel_attach()

Browse Source 
drm_panel_attach() return EBUSY if panel->connector already set,
which indicate that panel and connector are already bound.
Because the .bind() function might call multiple times, so it is
unnecessary to check its return value.
