[PATCH] xfs: remove inode log format typedef

[PATCH] xfs: remove inode log format typedef

[Darrick J. Wong]

From: Darrick J. Wong <darrick.wong@oracle.com>

Remove xfs_inode_log_format_t now that xfs_inode_log_format is
explicitly padded and therefore is a real on-disk structure.  This
enables xfs/122 to check the size of the structure.

(No functional changes, this is for benefit of xfsprogs)
