Log:
  When using an NFSv4 mount in the experimental nfs client with delegations
  being issued from the server, there was a case where an Open issued locally
  based on the delegation would be released before the associated vnode
  became inactive. If the delegation was recalled after the open was released,
  an Open against the server would not have been acquired and subsequent I/O
  operations would need to use the special stateid of all zeros. This patch
  fixes that case.
