Make all bluetooth drivers ignore the return value of hci_unregister_dev as it
always returns 0. In the next step, hci_unregister_dev can be modified to return
void.
Some of the drivers already ignore the return value (including btusb), hence,
this will increase consitency in the bluetooth drivers.
