USB: serial: cp210x: fix modem-control handling
The vendor request used to set the flow-control settings also sets the
state of the modem-control lines.
Add state variables to keep track of the modem-control lines to avoid
always asserting the lines whenever the flow-control settings are
updated.
This specifically also avoids asserting DTR/RTS when opening a port with
the line speed set to B0.
