[PATCH 01/13] USB: serial: ch341: fix initial modem-control state

[Johan Hovold <johan@kernel.org>]

DTR and RST will be asserted by the tty-layer when the port is opened
and deasserted on close (if HUPCL is set). Make sure the initial state
is not-asserted before the port is first opened as well.
