The implementation of qemu_put_compression_data only consider the case QEMUFile is writable, it can't work with a writable QEMUFile and does not provide any measure to prevent users from using it with a writable QEMUFile. For safety, it should be improved to avoid some issues.
ram_save_compressed_page can be refined based on the change of qemu_put_compression_data, very small improvement, but code looks better.
