tty_port: Move hupcl handling

Move the HUCPL handling from the end of close_port_start to the beginning
of close_port_end. What this actually does is change the ordering from

port shutdown
port->dtr_rts

to

port->dtr_rts
port shutdown

Some hardware drops the physical connection on shutdown so we must perform
the port operations before the shutdown.
