virtio_console: fix uninitialized variable use

[ Upstream commit 2055997f983c6db7b5c3940ce5f8f822657d5bc3 ]

We try to disable callbacks on c_ivq even without multiport
even though that vq is not initialized in this configuration.

Fixes: c743d09dbd01 ("virtio: console: Disable callbacks for virtqueues at start of S4 freeze")
