Fix serial_port DCD squelch 

Hi,

I had trouble with CTS serial port squelch (on microHAM USB Interface III).
It seems there is a bug in the hamlib code and I think the similar thing
should be done as has been done for the pttport, i.e. if the dcdport is
the same as the rigport, do not reopen it. Otherwise the serial port will
be reset to its default and it will key the radio PTT forever (because
the RTS line is reset on the port reopen). Patch attached
