Subject: [PATCH] Bluetooth: uart-ldisc: Fix memory leak

This is a partial, self-contained, minimal backport of commit
797fe796c4335b35d95d5326824513befdb5d1e9 upstream which fixes the memory
leak:

Bluetooth: uart-ldisc: Fix memory leak and remove destruct cb

We currently leak the hci_uart object if HCI_UART_PROTO_SET is never set
because the hci-destruct callback will then never be called.  This fix
removes the hci-destruct callback and frees the driver internal private
hci_uart object directly on tty-close. We call hci_unregister_dev() here
so the hci-core will never call our callbacks again (except destruct).
Therefore, we can safely free the driver internal data right away and
set the destruct callback to NULL.
