Description of problem: A client should be able to handle getting an EACCES error while doing a mount operation to reclaim state due to NFS4CLNT_RECLAIM_REBOOT being set. If the server returns RPC_AUTH_BADCRED because authentication failed when we execute "exportfs -au", then RECLAIM_COMPLETE will go a wrong way. After mount succeeds, all OPEN call will fail due to an NFS4ERR_GRACE error being returned.
