X-Git-Tag: v3.13-rc1~105^2~23^2^2~61^2~38

Bluetooth: Store the source address type of LE connections

When establishing LE connections, it is possible to use a public
address (if available) or a random address. The type of address
is only known when creating connections, so make sure it is
stored in hci_conn structure.
