ath11k: fix warn-on in disassociation
In multi AP VAP scenario, when user bring down the interfaces. mac80211 mark
the interface down for the duplicated VAP and removed from the
local->interfaces list. ath11k_mac_get_arvif() is dependent on
ieee80211_iterate_active_interfaces_atomic() API to find the vdev id
in a given radio. In disassociation path, ath11k_mac_get_arvif() not
able to find the given vdev id since that VAP is removed from the
local->interfaces list. since sta_state callback throws error, mac80211 log
the below WARN_ON_ONCE message.
Fixed it by storing the allocated_vdev_map in each radio structure to maintain
the created vdev id bits. so that we can directly mask this against the given
vdev_id to find out the ar from the vdev_id.
