[PATCH 2/2] drm/virtio: Propagate drm_encoder_init() errors

[Sebastian von Arx]

vgdev_output_init() ignores errors from drm_encoder_init(), so output
setup continues even when encoder initialization fails, for example
because of an allocation failure.

Check the return value and propagate the error to the caller.
