[PATCH 0/2] virtio: console: control queue race fixes

[Amit Shah <amit.shah@redhat.com>]

Hello,

The first patch here fixes the race seen by Miche.  He hasn't yet
reported back if this fixes the races he saw, but Joy Pu from Red Hat
tested this patch with hot-plugging/unplugging ports in a loop.
Before this patch, he saw some freezes as well as sysfs warnings.
After applying the patch, all was well.

The second patch can be folded into the series fixing S4 for
virtio-console.  It ensures all callbacks are disabled in the freeze
function.  This patch has a dependency on the 1st one in the sense the
double disabling of vq won't make sense w/o patch 1.

Please review and apply.
