sunrpc: move the close processing after do recvfrom method

sunrpc: "Move close processing to a single place"
(d7979ae4a050a45b78af51832475001b68263d2a) moved the
close processing before the recvfrom method. This may
cause the close processing never to execute. So this
patch moves it to the right place.
