Subject: vhost-vsock: fix orphan connection reset
From: Peng Tao <bergwolf@xxxxxxxxx>
commit c4587631c7bad47c045e081d1553cd73a23be59a upstream.
local_addr.svm_cid is host cid. We should check guest cid instead,
which is remote_addr.svm_cid. Otherwise we end up resetting all
connections to all guests.
