paycheck: allow src_extents to span the whole new partition size

In a previous fix, we allowed paycheck to consider the whole new
partition (beyond just the filesystem) as valid range for write
operations. However, since updates are done in place, they should also
be considered valid for read operations. This is now fixed.
