btrfs-progs: fi usage: change to output more info without root privilege
Although per device usage cannot be shown without root privilege, per profile usage can be shown. To achieve this, we just basically need to remove the check of nullness of chunkinfo in print_filesystem_usage_by_chunk(), because other functions except print_unused() properly handles chunkinfo by chunkcount, which is 0 if chunkinfo is null. As a result, "fi usage" always includes the information of "fi df".
