drm/fb-helper: Propagate errors from initial config failure
Make drm_fb_helper_initial_config() return an int rather than a bool so
that the error can be properly propagated. While at it, update drivers
to propagate errors further rather than just ignore them.
v2:
- cirrus: No cleanup is required, the top-level cirrus_driver_load()
will do it as part of cirrus_driver_unload() in its cleanup path.
