Trond Myklebust 830d5bd83a SUNRPC: Fix races in xs_nospace() ...

commit 06ea0bfe6e 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.
