BDRV_O_ALLOW_RDWR is a flag that tells whether qemu can internally reopen a node read-write temporarily because the user requested read-write for the top-level image, but qemu decided that read-only is enough for this node (a backing file). bdrv_reopen() is different, it is also used for cases where the user changed their mind and wants to update the options. There is no reason to forbid making a node read-write in that case.
