wifi: ath12k: Resolve multicast packet drop by populating key_cipher in ath12k_install_key()
Currently, the key_cipher in the ath12k_vif structure, which represents the
group cipher of the MLD AP, is populated when the link address matches the
ieee80211_vif address within ath12k_install_key().
However, in MLD AP, the link address and ieee80211_vif address can differ.
Due to this key_cipher is not populated and multicast packets don't get the
correct cipher information and resulting multicast packets drop.
To fix this, compare the link address with the arvif->bssid instead of the
ieee80211_vif address.
Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.3.1-00209-QCAHKSWPL_SILICONZ-1
