openvpnmsica: make adapter renaming non-fatal

For some users renaming adapter

    Local Area Connection > OpenVPN TAP-Windows6

mysteriously fails, see https://github.com/OpenVPN/openvpn-build/issues/187

Since renaming is just a "nice to have", make it non-fatal
and, in case of error, only log message and don't display messagebox.
