serdev: ttyport: fix tty locking in close
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: cd6484e1830b ("serdev: Introduce new bus for serial attached devices")
