      NFSv4: When returning a delegation, don't reclaim an incompatible open mode. · 39f897fd
      NeilBrown authored
      It is possible to have an active open with one mode, and a delegation
      for the same file with a different mode.
      In particular, a WR_ONLY open and an RD_ONLY delegation.
      This happens if a WR_ONLY open is followed by a RD_ONLY open which
      provides a delegation, but is then close.
      
      When returning the delegation, we currently try to claim opens for
      every open type (n_rdwr, n_rdonly, n_wronly).  As there is no harm
      in claiming an open for a mode that we already have, this is often
      simplest.
      
      However if the delegation only provides a subset of the modes that we
      currently have open, this will produce an error from the server.
      
      So when claiming open modes prior to returning a delegation, skip the
      open request if the mode is not covered by the delegation - the open_stateid
      must already cover that mode, so there is nothing to do.
