xfs: Convert linux-2.6/ files to new logging interface

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.
