Bluetooth: Use hci_connect_sco directly
hci_connect is a super function for connecting hci protocols. But the voice_setting parameter (introduced in subsequent patches) is only needed by SCO and security requirements are not needed for SCO channels. Thus, it makes sense to have a separate function for SCO.
