drm: Skip drm_mode_config_validate() for !modeset
drm_mode_config_init() may not have been called when the driver/device
doesn't support modeset. That will cause drm_mode_config_validate()
to oops. Skip the validation for !modeset.
TODO: We may want to consider calling drm_mode_config_init()
unconditionally to avoid similar issues elsewhere...
Fixes: 74d2aacbe840 ("drm: Validate encoder->possible_clones")
