[PATCH 4.8 14/33] vhost-vsock: fix orphan connection reset

[Greg Kroah-Hartman]

4.8-stable review patch.  If anyone has any objections, please let me know.

------------------

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.
