smb3: add reconnect tracepoints
Add tracepoints for reconnecting an smb3 session
Example output (from trace-cmd) with the patch
(showing the session marked for reconnect, the stat failing, and then
the subsequent SMB3 commands after the server comes back up).
The "smb3_reconnect" event is the new one.
