CIFS: Set reconnect instance to one initially

Currently we set reconnect instance to zero on the first
connection but this is not convenient because we need to
reserve some special value for credit handling on reconnects
which is coming in subsequent patches. Fix this by starting
with one when initiating a new TCP connection.
