Btrfs: kill free_space pointer from inode structure
Inodes always allocate free space with BTRFS_BLOCK_GROUP_DATA type, which means every inode has the same BTRFS_I(inode)->free_space pointer. This shrinks struct btrfs_inode by 4 bytes (or 8 bytes on 64 bits). Signed-off-by: Li Zefan <lizefan@huawei.com>
