Description
The bug is caused by 82d5994520c239da1b6edf1b24e08138ae0c753d(MDEV-26110), as field_ref_zero is initialized only for xtrabackup_backup_func(), but not for xtrabackup_prepare_func().
The bug can be repeated with the following change to an existing test:

The suggested fix is to move field_ref_zero allocation/deallocation from xtrabackup_backup_func() to it's caller main_low().
