When expanding file for a write into a hole, we were not updating total length of inode's extents properly. Move the update of i_lenExtents into udf_do_extend_file() so that both expanding of file by truncate and expanding of file by writing beyond EOF properly update the length of extents. As a bonus, we also correctly update the length of extents when only part of extents can be written.
