Description
In the Linux kernel, the following vulnerability has been resolved:

wifi: mac80211: require a peer station for TDLS setup confirm

It's nonsense for the setup confirm to go to station that
doesn't even exist, and it hits a warning when building
the frame:

WARN_ON_ONCE(!sta || !ap_sta)

Only accept WLAN_TDLS_SETUP_CONFIRM when the station is
already there as a TDLS station. Need to copy the call
to ieee80211_tdls_prep_mgmt_packet() since the existing
WLAN_TDLS_DISCOVERY_REQUEST already falls through to it.
