[PATCH] hpfs: Whitespace and Codingstyle cleanup for dir.c

[Jesper Juhl <jesper.juhl@gmail.com>]

Whitespace and CodingStyle cleanup for fs/hpfs/dir.c

While reading through fs/hpfs/dir.c I ran across lots of cases of multiple
statements on a single line that made some bits of the file quite confusing
to read. This patch cleans that up and also make sure labels are placed at
column 1, removes trailing whitespace and a few other minor CodingStyle nits.

There are some very long lines in this file that would be a lot more readable 
(IMHO) if broken up to fit within 80 cols. This patch does not do that, but
if wanted I can submit an aditional patch on top of this one to do that.
