Log:
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.
