xfs_fsr: fix test for short write

Clang found this one too, as a dead nested assignment.

The point is to see if we write all the bytes; but the initial
assignment is backwards.  It's safe in the end, because if they
weren't already equal anyway, we'd have exited prior to this, but
it's worth fixing up for clarity.
