[PATCH 10/30] libxfs: Minor cleanup and bug fix sync

[Dave Chinner <david@fromorbit.com>]

From: Dave Chinner <dchinner@redhat.com>

These bring all the small single line comment, whitespace and minor
code differences into sync with the kernel code. Anything left at
this point is an intentional difference.
