Chuck Lever d097e5b5a1 xprtrdma: Return -ENOBUFS when no pages are available ...

commit a8f688ec43 upstream.

The use of -EAGAIN in rpcrdma_convert_iovs() is a latent bug: the
transport never calls xprt_write_space() when more pages become
available. -ENOBUFS will trigger the correct "delay briefly and call
again" logic.
