[PATCH RESEND] nilfs2: fix i_xattr comment to note it is unused

[Yuto Ohnuki]

NILFS2 does not currently support extended attributes. Update the
comment for @i_xattr in struct nilfs_inode_info to clarify that it is
reserved but unused.

Thank you.

Viacheslav, could you please pick this up directly and queue it for
the next cycle (with the following Acked-by tag)?

There's been discussion about removing the on-disk inode xattr field
to implement atime, so if it's no longer needed for that reason, you
can drop it.

However, since this is an on-memory inode field, I think it's okay to
leave the field itself in place until its handling is decided.

Regards,
Ryusuke Konishi
