virtio: console: Make read() return -ENODEV on hot-unplug When a port is hot-unplugged while an app was blocked on a read() call, the call was unblocked but would not get an error returned. Return -ENODEV to ensure the app knows the port has gone away. Signed-off-by: Amit Shah <amit.shah@redhat.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
