Eric Blake a5068244b4 nbd: Don't inf-loop on early EOF ... Commit 7d3123e converted a single read_sync() into a while loop that assumed that read_sync() would either make progress or give an error. But when the server hangs up early, the client sees EOF (a read_sync() of 0) and never makes progress, which in turn caused qemu-iotest './check -nbd 83' to go into an infinite loop. Rework the loop to accomodate reads cut short by EOF.
