virtio_console: reset on out of memory

commit 5c60300d68da32ca77f7f978039dc72bfc78b06b upstream.

When out of memory and we can't add ctrl vq buffers,
probe fails. Unfortunately the error handling is
out of spec: it calls del_vqs without bothering
to reset the device first.

To fix, call the full cleanup function in this case.
