Chen Zhongjin edf7284a98 Bluetooth: Fix not cleanup led when bt_init fails 
[ Upstream commit 2f3957c7eb ]

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:
