Bluetooth: Fix not cleanup led when bt_init fails
bt_init() calls bt_leds_init() to register led, but if it fails later,
bt_leds_cleanup() is not called to unregister it.
This can cause panic if the argument "bluetooth-power" in text is freed
and then another led_trigger_register() tries to access it:
BUG: unable to handle page fault for address: ffffffffc06d3bc0
RIP: 0010:strcmp+0xc/0x30
Call Trace:
