From: Johan Hedberg <johan.hedberg@xxxxxxxxx>
To be consistent with the remote address info in hci_conn we want it to
also contain the local identity address information. The struct will
contain the actual address used for the connection while a connection
process is in place but as soon as we have a successful connection the
identity address should be tracked instead.
This patch updates the code to set the src and src_type values to point
at the identity address in the hci_le_conn_complete_evt function. The
identity address can either be a public address or a static random
address.
