Dave Young f74c77cb11 bluetooth: scheduling while atomic bug fix 
Due to driver core changes dev_set_drvdata will call kzalloc which should be
in might_sleep context, but hci_conn_add will be called in atomic context

Like dev_set_name move dev_set_drvdata to work queue function.

oops as following:
