Message-Id: <20250204-unlink_link_arvif_from_chanctx-v1-6-675bd4cea339@oss.qualcomm.com>

Subject: [PATCH 6/8] wifi: ath12k: relocate a few functions in mac.c
An upcoming change will invoke ath12k_mac_init_arvif(),
ath12k_mac_assign_link_vif(), and ath12k_mac_unassign_link_vif() from a
line located above their current definition. Hence, relocate these
functions to above so that these can be invoked later on.
No functionality changes. Compile tested only.
