nfsd4: remove unnecessary comment
For the most part readers of cl_cb_state only need a value that is "eventually" right. And the value is set only either 1) in response to some change of state, in which case it's set to UNKNOWN and then a callback rpc is sent to probe the real state, or b) in the handling of a response to such a callback. UNKNOWN is therefore always a "temporary" state, and for the other states we're happy to accept last writer wins. So I think we're OK here. Signed-off-by: J. Bruce Fields <bfields@redhat.com>
