First, bdrv_open_child() expects all options for the child to be prefixed by the child's name (and a separating dot). Second, bdrv_open_child() does not take ownership of the QDict passed to it but only extracts all options for the child, so if a QDict is created for the sole purpose of passing it to bdrv_open_child(), it needs to be freed afterwards. This patch makes vvfat adhere to both of these rules.
