wifi: ath12k: Consistently use ath12k_vif_to_arvif()

Helper function ath12k_vif_to_arvif() exists to retrieve a struct
ath12k_vif from a struct ieee80211_vif. However, in multiple places
this logic is open-coded with inline typecasting. Since the
typecasting prevents the compiler from type-checking the source and
destination, update the driver to consistently use the helper
function.

No functional changes, compile tested only.
