Eli Qiao bafc0f8d9c Ignore errorcode=4 when executing cryptsetup remove command ... If an attached encrypted volume is failed to detach from the instance when deleting that instance, user can not delete that instance at all. This patch adds 4 in check_exit_code when executing `cryptsetup remove` command to eat that exception. PS: exit_code = 4 indicate ENODEV error which means no device(also includes the crypt device inactive).
