USB: serial: ch341: fix initial modem-control state
commit 4e2da44691cffbfffb1535f478d19bc2dca3e62b upstream.
DTR and RTS 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.
