[PATCH 03/12] xfs: Convert linux-2.6/ files to new logging interface

[Dave Chinner <david@fromorbit.com>]

From: Dave Chinner <dchinner@redhat.com>

Convert the files in fs/xfs/linux-2.6/ to use the new xfs_<level>
logging format that replaces the old irix inherited cmn_err()
interfaces. While there, also convert naked printk calls to use the
relevant xfs logging function to standardise output format.
