Subject: [PATCH 4.14 106/135] vsock/virtio: reset connected sockets on device removal
4.14-stable review patch. If anyone has any objections, please let me know.
------------------
[ Upstream commit 85965487abc540368393a15491e6e7fcd230039d ]
When the virtio transport device disappear, we should reset all
connected sockets in order to inform the users.
