Thus in case the size of filesystem was such that the last group had the minimal size (50 blocks + metadata overhead), the code in adjust_fs_info() decided the group is unneeded, removed it, and in some cases the resizing then failed with ENOSPC. Fix the issue by properly accounting for s_first_data_block in calculate_minimum_resize_size().
