kernel - Optimize sync and msync for tmpfs and nfs

* Flesh-out the vfs_sync API and implement vhold/vdrop callbacks
  (used by NFS).

* Use MNTK_THR_SYNC in tmpfs and finish implementing it in nfs.  This
  will optimize sync and msync for these filesystems.

* In both cases inode attributes are either synchronous or don't involve
  any VFS work to flush, so we don't have to use VISDIRTY.
