UDF: coding style fixups

This patch does additional coding style fixup.  Initially the code is being
distorted by Lindent (in my patches sent not very long ago) and fixed in
the followup patches but this stuff was accidently missed.

New and old compiled files were compared with cmp to check for being
identically.  So the patch will not break the kernel.
