When using MSG_WAITALL, soreceive() can sleep while processing the
receive buffer of a stream socket. Then a new pair of control and
data mbuf can be appended to the mbuf queue. In this case, terminate
the loop with a short read to prevent a panic. Userland should
read the control message with the next system call.
