Title: Wip 10166: fiemap or FileStore::do_sparse_copy_range bug

If calling clone_range and zero filled sections is at the ending of src
range, the target fd won't write zero filled sections. If target's
origin size shorter than needed, it will cause inconsistence between
two fd's desired range.

Fix bug #10166
