Fake error "Connection ... was not closed, closing automatically"

[zerikv]

I noticed an error stack in the console about some connections that was not closed.
This log is produced by the method BaseOverthereConnection#finalize().
I think is not always right for CIFS and SMB connection, because the state connected is set in the constructor of CifsProcessConnection or SmbProcessConnection before calling the method connect().
Thus if the creation of the connection failed (for example a SmbConnection when SMB v2 is disabled) this error is logged but no connection has been actually opened.
