Call CTDB's smnotify when starting Ganesha.
So V3 Clients will reclaim their locks when Ganesha restarts.
This will help in the cases when the system's sm-notify fails

Skip setattr if the create has already handled them.
Most of the clients only set mode with create and all other attributes
are set to deafault.
An extra setattr call will be made only if the client wants to use non
default values.
