client_protocol_reconnect - do not send notify of CHILD_DOWN event if errno from transport_connect() was EINPROGRES
client_protocol_reconnect - do not send notify of CHILD_DOWN event if errno from transport_connect() was EINPROGRES

This bug was racing between a CHILD_UP from poll thread resulting from the event_register() of the new socket called in fuse thread. CHILD_UP would sometimes overtake the CHILD_DOWN for EINPROGRESS. So replicate would receive CHILD_DOWN as the latest event. This resulted in self-heal not happening etc.
