wifi: ath12k: Optimize the mac80211 hw data access

Currently mac80211 hw data is accessed by convert the hw to radio (ar)
structure and then radio to hw structure which is not necessary in some
places where mac80211 hw data is already present. So in that kind of
places avoid the conversion and directly access the mac80211 hw data.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1
