[PATCH 14/18] Bluetooth: Remove unused hci-destruct cb

[David Herrmann <dh.herrmann@googlemail.com>]

The hci-destruct callback is not used by any driver so we can remove it. There
is no reason to keep it alive, anymore. Drivers can free their internal data on
driver-release and we do not need to provide a public destruct callback.

Internally, we still use a destruct callback inside of hci_sysfs.c. This one is
used to correctly free our hci_dev data structure if no more users have a
reference to it.
