drm/meson: Fix error handling when afbcd.ops->init fails
When afbcd.ops->init fails we need to free the struct drm_device. Also
all errors which come after afbcd.ops->init was successful need to exit
the AFBCD, just like meson_drv_unbind() does.
Fixes: d1b5e41e13a7e9 ("drm/meson: Add AFBCD module driver")
