tty: fix ldisc lock inversion trace This is caused by tty_release using tty_lock_pair to lock both sides of the pty/tty pair, and then tty_ldisc_release dropping and relocking one side only. We can drop both fine, so drop both to avoid any lock ordering concerns. Rework the release path to fix the new locking model.
