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.
