udf: Fix extension of the last extent in the file
[ Upstream commit 83c7423d1eb6806d13c521d1002cc1a012111719 ]
When extending the last extent in the file within the last block, we
wrongly computed the length of the last extent. This is mostly a
cosmetical problem since the extent does not contain any data and the
length will be fixed up by following operations but still.
