* xfs_inode_item_format_extents - convert in-core extents to on-disk form

* the in-core extent as we place them into the on-disk inode. In this case, we
* need to do this conversion before we write the extents into the log. Because
* we don't have the disk inode to write into here, we allocate a buffer and
* format the extents into it via xfs_iextents_copy(). We free the buffer in
* the unlock routine after the copy for the log has been made.
*
* In the case of the data fork, the in-core and on-disk fork sizes can be
* different due to delayed allocation extents. We only log on-disk extents
* here, so always use the physical fork size to determine the size of the
* buffer we need to allocate.
