btrfs: fix free space calculation in dump_space_info()
In btrfs, btrfs_space_info's bytes_may_use is treated as fs used space, as what we do in reserve_metadata_bytes() or btrfs_alloc_data_chunk_ondemand(), so in dump_space_info(), when calculating free space, we should also subtract btrfs_space_info's bytes_may_use.
