tty:n_gsm.c: destroy port by tty_port_destroy()
According to the comment of tty_port_destroy():
When a port was initialized using tty_port_init, one has to destroy
the port by tty_port_destroy();
tty_port_init() is called in gsm_dlci_alloc()
so tty_port_destroy() needs to be called in gsm_dlci_free()
