Subject: [PATCH 09/44] tty: n_tty, set tty_ldisc_ops::owner

Set tty_ldisc_ops::owner to THIS_MODULE. This has no effect currently as
n_tty cannot be built as a module. If someone ever tries to modularize
tty, we wouldn't manage module's reference count as in other ldiscs. So
fix this just in case.
