[PATCH] Bluetooth: hci_ldisc: Fix for pty driver

tty_set_termios() should be called with slave side of pty driver. So, If tty driver is pty master, it needs to be switched to ->link. Also, tiocmget() and tiocmset() operations are optional so we need NULL check for some drivers missing the operations like pty. Reported-by: syzbot+a950165cbb86bdd0
