Backport of upstream fix to 1.27.3

Description of problem:

When creating a bridge, and putting an Ethernet slave and a Wlan slave (which has been configured as an AP), authentication will always fail when connecting to that AP.


Version-Release number of selected component (if applicable):

2.9-2

How reproducible:

nmcli conn add con-name "Bridge 0" \
    type bridge ifname br0 \
    connection.autoconnect true \
    ipv4.method "manual" \
    ipv4.address "$LOCALIP/$LOCALPREFIX" \
    +ipv4.routes "224.0.0.0/4"

nmcli conn delete "Bridge slave 0"

nmcli conn add con-name "Bridge slave 0" \
    master "Bridge 0" \
    type ethernet ifname eth1

nmcli conn delete "Bridge slave 1"

nmcli conn add con-name "Bridge slave 1" \
    master "Bridge 0" \
    type wifi ifname wlan0 \
    mode ap ssid "$ssid" \
    802-11-wireless.band "bg" \
    802-11-wireless-security.key-mgmt "wpa-psk" \
    802-11-wireless-security.psk "$passphrase"

nmcli conn up "Bridge 0"

and now try to authenticate to that AP.

Steps to Reproduce:
1. Create bridge.
2. Add Ethernet and WLAN slaves (WLAN must be configured as AP).
3. Bring up bridge and try to connect to it.

Actual results:

Authentication fails.

Expected results:

Authentication should succeed.
