Commit Message

From: Sriram R <quic_srirrama@quicinc.com>

Currently ieee80211_vif/ahvif is passed as argument for all vif
related control path functions that are being called from
mac80211 ops. With MLO support being added multiple link vifs can
be part of an ieee80211_vif/ahvif and all these functions will need
link id along with ieee80211_vif/ahvif to be passed to fetch the
corresponding link vif (arvif) to which the control/config applies.
Also all these functions need to validate the locking dependency before
dereferencing and start using the link vifs.

To avoid these redundant link dereferences and validations,
limit ieee80211_vif/ahvif argument to mac80211 ops unless
otherwise really required. Do link vif dereference and locking only in
mac80211 ops.
Replace vif arg with ath12k_link_vif and internally fetch ath12k_vif(ahvif)
and vif(ieee80211_vif) if required on other functions.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
