btrfs.c: use print_array
* btrfs.c (print_btrfs_data_container_logical_ino, print_btrfs_data_container_ino_path, print_uint64, print_btrfs_ioctl_search_header, print_objectid_callback, print_btrfs_ioctl_space_info): New functions. (btrfs_print_logical_ino_container, btrfs_print_ino_path_container): Rewrite printers of struct btrfs_data_container.val array using print_array. (btrfs_print_qgroup_inherit): Rewrite printer of struct btrfs_qgroup_inherit.qgroups array using print_array. (btrfs_print_tree_search): Rewrite printer of struct btrfs_ioctl_search_header array using print_array. (btrfs_ioctl): Rewrite printer of struct btrfs_ioctl_send_args.clone_sources and struct btrfs_ioctl_space_args.spaces using print_array.
