[RFC PATCH v2 8/9] virtio/vsock: check SO_RCVLOWAT before wake up reader

[Arseniy Krasnov]

This adds extra condition to wake up data reader: do it only when number
of readable bytes >= SO_RCVLOWAT. Otherwise, there is no sense to kick
user,because it will wait until SO_RCVLOWAT bytes will be dequeued.
