[ Upstream commit 61a5ab72edea7ebc3ad2c6beea29d966f528ebfb ]
hci_store_wake_reason() wrongly parses event HCI_Connection_Request as HCI_Connection_Complete and HCI_Connection_Complete as HCI_Connection_Request, so causes recording wakeup BD_ADDR error and potential stability issue, fix it by using the correct field.
