[PATCH 03/15] xfs: remove the xfs_extent_t typedef

[Christoph Hellwig <hch@lst.de>]

There are almost no users of the typedef left, kill it and switch the
remaining users to use the underlying struct.

Also fix up the comment about the struct xfs_extent definition to be
correct and read more easily.
