smb3: add dynamic trace points for socket connection
In debugging user problems with ip address/DNS issues with
smb3 mounts, we sometimes needed additional info on the hostname
and ip address.
Add two tracepoints, one to show socket connection success
and one for failures to connect to the socket.
Sample output:
