Haoxiang Li 7c7f1bfdb2 mcb: fix a double free bug in chameleon_parse_gdd() 
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.
