nfsd4: probe callback channel only once
Our callback code doesn't actually handle concurrent attempts to probe the callback channel. Some rethinking of the locking may be required. However, we can also just move the callback probing to this case. Since this is the only time a client is "confirmed" (and since that can only happen once in the lifetime of a client), this ensures we only probe once. Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu>
