[Qemu-devel] [PATCH v3 19/23] blockdev: Drop DriveInfo member enable_auto_del

[Markus Armbruster <armbru@redhat.com>]

Commit 2d246f0 introduced DriveInfo member enable_auto_del to
distinguish DriveInfo created via drive_new() from DriveInfo created
via qmp_blockdev_add().  The latter no longer exist.  Drop
enable_auto_del.
