vmci/vsock: check SO_RCVLOWAT before wake up reader

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. This
check is performed in vsock_data_ready().
