[RFC PATCH] xfs: fix calculation of freed inode cluster blocks

[Ben Myers <bpm@xxxxxxx>]

rec.ir_startino is an agino rather than an ino.  Use the correct macro
when dealing with it in xfs_difree.

---

This is very lightly tested so it's RFC.  Looks like using "ino to
agbno" is actually harmless when you pass in an agino, so there
shouldn't have been any trouble caused by this one.
