serial-port: fail open/reopen after a serial port has been forced close
After a MMSerialPort object is forced close, it may be opened again if some
other object still holds a reference to it. When the MMSerialPort object is
eventually disposed, mm_serial_port_close_force is invoked on the object but
does nothing as 'priv->forced_close' is already set to TRUE. 'priv->watch_id'
is still active, which could potentially lead to a crash if data_available is
called after the MMSerialPort object is finalized. This patch prevents such a
scenario by failing mm_serial_port_open / mm_serial_port_reopen after the
MMSerialPort has been forced close.
