[PATCH] remove nonsense force-casts from ocfs2

[Al Viro <viro@ftp.linux.org.uk>]

	endianness annotations in networking code had been in place for
quite a while; in particular, sin_port and s_addr are annotated as
big-endian.  Code in ocfs2 had __force casts added apparently to shut the
sparse warnings up; of course, these days they only serve to *produce*
warnings for no reason whatsoever...
