[PATCH 39/60] xfs: separate icreate log format definitions from xfs_icreate_item.h

[Dave Chinner]

From: Dave Chinner <dchinner at redhat.com>

The on disk log format definitions for the icreate log item are
intertwined with the kernel-only in-memory log item definitions.
Separate the log format definitions out into their own header file
so they can easily be shared with userspace.
