[BLUETOOTH]: rfcomm tty BUG_ON() code fix
1) In tty.c the BUG_ON at line 115 will never be called, because the the before list_del_init in this same function. 115 BUG_ON(!list_empty(&dev->list)); So move the list_del_init to rfcomm_dev_del 2) The rfcomm_dev_del could be called from diffrent path (rfcomm_tty_hangup/rfcomm_dev_state_change/rfcomm_release_dev), So add another BUG_ON when the rfcomm_dev_del is called more than one time.
