This function is used to put the hidden and secondary disks in read-write mode before launching the backup job, and back in read-only mode afterwards. This patch does the following changes: - Use an options QDict with the "read-only" option instead of passing the changes as flags only. - Simplify the code (it was unnecessarily complicated and verbose). - Fix a bug due to which the secondary disk was not being put back in read-only mode when writable=false (because in this case orig_secondary_flags always had the BDRV_O_RDWR flag set). - Stop clearing the BDRV_O_INACTIVE flag. The flags parameter to bdrv_reopen_queue() becomes redundant and we'll be able to get rid of it in a subsequent patch.
