Chuck Lever 3d4cf35bd4 xprtrdma: Reply buffer exhaustion can be catastrophic ... Not having an rpcrdma_rep at call_allocate time can be a problem. It means that send_request can't post a receive buffer to catch the RPC's reply. Possible consequences are RPC timeouts or even transport deadlock. Instead of allowing an RPC to proceed if an rpcrdma_rep is not available, return NULL to force call_allocate to wait and try again.
