[PATCH 3/3] Bluetooth: Don't check source address in SCO bind function

[Marcel Holtmann <marcel@holtmann.org>]

Checking the source address in SCO bind function will prevent from
having an incoming and outgoing SCO socket. However that might be
needed in case of multiple SCO connections on a single device.
