    security: plug regression introduced in disk probe logic
    
    wrong sizeof operand meant that security manager private data
    was overlaying the allowDiskFormatProbing member of struct
    _virSecurityManager.  This reopens disk probing, which was
    supposed to be prevented by the solution to CVE-2010-2238.
    
    * src/security/security_manager.c
    (virSecurityManagerGetPrivateData): Use correct offset.
