core: don't set BR/EDR support when no flags present

The logic for setting the BR/EDR supported flag checked for the
non-presence of the BR/EDR Unsupported flag without checking whether
any flags were present at all.

This meant all LE-only devices that returned Scan Response Data were
being marked as supporting BR/EDR, since the flag was only set in the
initial AD and not the SRD.
