wireless/bluetooth: Support removable bluetooth modules.

Browse Source 
This bluetooth stack remains in an inconsistent state when
the bluetooth HCI module is removed. This change adds a
bt_netdev_unregister function that can be used to clean up
after a module is removed. Some global variables are also
set to their default values.
