Backup: don't do copy-on-read in before_write_notifier
We will copy data in before_write_notifier to do backup.
It is a nested I/O request, so we cannot do copy-on-read.
The steps to reproduce it:
1. -drive copy-on-read=on,... // qemu option
2. drive_backup -f disk0 /path_to_backup.img // monitor command
