Various fixes to the NFS Directio support.
- Fix for a bug where a close would not wait for all (directio)
  dirty buffers to drain. The nfsnode was not marked NMODIFIED
  when there were directio dirtied buffers pending, causing this.
- No reason to vhold/vrele the vp when enqueueing DirectIO requests
  for the nfsiods. The vnode can't really go way since the close
  has to wait for these requests to drain.
