smb3: on reconnect set PreviousSessionId field 



commit b2adf22fdfba85a6701c481faccdbbb3a418ccfc upstream.

The server detects reconnect by the (non-zero) value in PreviousSessionId
of SMB2/SMB3 SessionSetup request, but this behavior regressed due
to commit 166cea4d
("SMB2: Separate RawNTLMSSP authentication from SMB2_sess_setup")
