  The NFSv4.1 server should return NFSERR_BACKCHANBUSY instead of NFS_OK.
  
  When an NFSv4.1 session is busy due to a callback being in progress,
  nfsrv_freesession() should return NFSERR_BACKCHANBUSY instead of NFS_OK.
  The only effect this has is that the DestroySession operation will report
  the failure for this case and this probably has little or no effect on a
  client. Spotted by inspection and no failures related to this have been
  reported.
