NFSv4: Clean up some shutdown loops

Browse Source 
If a SEQUENCE call receives -EIO for a shutdown client, it will retry the
RPC call.  Instead of doing that for a shutdown client, just bail out.

Likewise, if the state manager decides to perform recovery for a shutdown
client, it will continuously retry.  As above, just bail out.
