btrfs-progs: qgroup: add sync option to 'qgroup show'
The 'qgroup show' command does not synchronize filesystem. Therefore, 'qgroup show' may not display the correct value unless synchronized with 'filesystem sync' command etc. So add the '--sync' option so that we can choose whether or not to synchronize when executing the command.
