[PATCH 15/26] xfs: redefine xfs_ictimestamp_t

["Darrick J. Wong" <darrick.wong@xxxxxxxxxx>]

From: Darrick J. Wong <darrick.wong@xxxxxxxxxx>

Source kernel commit: 30e05599219f3c15bd5f24190af0e33cdb4a00e5

Redefine xfs_ictimestamp_t as a uint64_t typedef in preparation for the
bigtime functionality.  Preserve the legacy structure format so that we
can let the compiler take care of the masking and shifting.
