nfs/filelayout: set layoutcommit depending on write verifier
Following http://www.rfc-editor.org/errata_search.php?rfc=5661&eid=2751
Don't set layoutcommit for commit_through_mds case.
For FILE_SYNC writes, don't set layoutcommit.
For DATA_SYNC wirtes, set layout commit right after wirtes done.
For UNSTABLE writes, set layout commit when commit done.
