pNFS: Tighten up locking around DS commit buckets I'm not aware of any bugreports around this issue, but the locking around the pnfs_commit_bucket is inconsistent at best. This patch tightens it up by ensuring that the 'bucket->committing' list is always changed atomically w.r.t. the 'bucket->clseg' layout segment tracking.
