Subject: [PATCH] NFSv4: Schedule recovery if nfs40_walk_client_list() is
 interrupted

If a timeout or a signal interrupts the NFSv4 trunking discovery
SETCLIENTID_CONFIRM call, then we don't know whether or not the
server has changed the callback identifier on us.
Assume that it did, and schedule a 'path down' recovery...
