Johan Hovold ce42ed5ae8 serdev: ttyport: fix tty locking in close ...

commit 90dbad8cd6 upstream.

Make sure to hold the tty lock as required when calling tty-driver
close() (e.g. to avoid racing with hangup()).

Note that the serport active flag is currently set under the lock at
controller open, but really isn't protected by it.

Fixes: cd6484e183 ("serdev: Introduce new bus for serial attached devices")
