From: Sriram R <quic_srirrama@xxxxxxxxxxx>
Since vif and sta objects of different radios are added to same
local hw list in mac80211, additional checks need to be done
in driver to ensure we are processing the intended vif
and sta corresponding to the radio when the vif and sta mac80211
iterator utils are used from driver.
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
