NFSv4.1/pnfs: Separate out metadata and data consistency for pNFS
The LAYOUTCOMMIT operation means different things to different layout types. For blocks and objects, it is both a data and metadata consistency operation. For files and flexfiles, it is only a metadata consistency operation. This patch separates out the 2 cases, allowing the files/flexfiles layout drivers to optimise away the data consistency calls to layoutcommit.
