[Tux3] Further sync for inode.c

[OGAWA Hirofumi]

Hi,

Those are to get closer to kernel. And probably, we wanted inode.c in
userland, so this patches modify some part of inode.c to prepare. And
some random cleanup is also there.

Please review and pull it.

With above, we can also copy user/inode.c to fs/tux3/ with one line change.

This functions may rewrite in kernel completely, I'm not sure. Well,
this difference wouldn't matter at least for now.

Thanks.
