mcb: fix a double free bug in chameleon_parse_gdd() commit 7c7f1bfdb2249f854a736d9b79778c7e5a29a150 upstream. In chameleon_parse_gdd(), if mcb_device_register() fails, 'mdev' would be released in mcb_device_register() via put_device(). Thus, goto 'err' label and free 'mdev' again causes a double free. Just return if mcb_device_register() fails.
