[PATCH] wifi: ath11k: Consistently use ath11k_vif_to_arvif()

From: Jeff Johnson
Date: Mon Aug 21 2023 - 10:13:59 EST


Helper function ath11k_vif_to_arvif() exists to retrieve a struct
ath11k_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.
