A non-MLD station's EAPOL and data frames are tagged with link_id ==
IEEE80211_LINK_UNSPECIFIED, which now skips the per-link lookup in
mt7996_mac_write_txwi() and leaves omac_idx/band_idx/wmm_idx at slot
0. When the radio also runs AP VAPs the station's omac is non-zero
(get_omac_idx() prefers HW BSSID slots 1-3), so its EAPOL frames
egress from the wrong BSS and the 4-way handshake times out even
though association succeeds.
In mt7996_tx_prepare_skb(), resolve the link from the peer wcid when
link_id is UNSPECIFIED and the wcid is not the global entry, restoring
the pre-MLO behaviour for station traffic.
