qemu-img: Flush stdout before before potential stderr messages
During 'qemu-img create ... 2>&1', if --quiet is not in force, we can end up with buffered I/O in stdout that was produced before failure, but which appears in output after failure. This is confusing; the fix is to flush stdout prior to attempting anything that might produce an error message. Several iotests demonstrate the resulting ordering change now that the merged outputs now reflect chronology. (An even better fix would be to avoid printf from within block.c altogether, but that's much more invasive...)
