commit 8ab18d71de8b07d2c4d6f984b718418c09ea45c5 upstream.
The check in vmci_transport_peer_detach_cb should only allow a
detach when the qp handle of the transport matches the one in
the detach message.
Testing: Before this change, a detach from a peer on a different
socket would cause an active stream socket to register a detach.
