SUNRPC: Fix races in xs_nospace()
commit 06ea0bfe6e6043cb56a78935a19f6f8ebc636226 upstream.
When a send failure occurs due to the socket being out of buffer space,
we call xs_nospace() in order to have the RPC task wait until the
socket has drained enough to make it worth while trying again.
The current patch fixes a race in which the socket is drained before
we get round to setting up the machinery in xs_nospace(), and which
is reported to cause hangs.
