[PATCH] AP MLD: set the link address only when the non-AP MLD is not added to the driver

[Michael-CY Lee]

Once the non-AP MLD is added to the driver, the driver handles the
address translation so that hostapd receives mgmt. with SA/DA being
translated into MLD addresses.

If the authentication request is re-transmitted with transaction being 1,
SA of the re-transmitted request is translated into MLD address by the
driver, and then in the function handle_auth(),
sta->mld_info.links[].peer_addr is replaced by the MLD address.

Therefore, only when the STA is not added into the driver that the link
address can be set.
