xfs: only assert new size for datafork during truncate extents

Browse Source 
The assertion functions properly because we currently only truncate the
attr to a zero size. Any other new size of the attr is not preempted.
Make this assertion is specific to the datafork, preparing for
subsequent patches to truncate the attribute to a non-zero size.
