Client library: qfs protocol state machine: fix authentication handshake handling by setting lookup and authenticate ops sequence number to -1 in connection reset method, as the ops might not be in flight yet, and in such case cancel that sets sequence number to -1 will no be invoked. Fix re-queuing, and retry logic for ops with no owner, do not cancel these until the retries are exhausted. (It seems that at the moment only sort master’s running status file delete code issues ops with no owner.)
