Treat devices advertising random addr. as LE only

Some remote devices use random addresses, but are not setting the
"BR/EDR not supported" flag. Thus we try to connect to the device using
BR/EDR.

This patch ignores the ADV flags if the device is using a random
address and always makes the connection over the LE transport.
