Actually, this is wrong.  Remember, the swab functions are used to
swap *from* and *to* host byte order and on-disk order.  So yes, there
was a bug in that we were also using the f->i_extra_size, but using
t->i_extra_size is also going to be wrong in some cases.  That's what
the hostorder parameter to ext2fs_swap_inode_full() is for.
