[RFC v3 6/7] Vhost-vsock: Avoid lockdep warning

[Claudio Imbrenda <imbrenda@linux.vnet.ibm.com>]

From: Claudio Imbrenda <imbrenda@de.ibm.com>

release the lock on the child socket before calling
virtio_transport_send_response . Thid avoids complaints from lockdep, but
I'm not sure it won't introduce race conditions.
This patch should be considered more as a hint, unless someone more
knowledgeable can confirm that it won't create problems.
