btrfs-progs: qgroup show: refine error messages

When qgroup show is called on a filesystem that does not have quotas
enabled, the error message is very unclear:

  ERROR: can't perform the search - No such file or directory
  ERROR: can't list qgroups: No such file or director

Remove the error from low level helper and let the command handler
decide what to print.
