wifi: ath12k: clear stale link mapping of ahvif->links_map

When an arvif is initialized in non-AP STA mode but MLO connection
preparation fails before the arvif is created
(arvif->is_created remains false), the error path attempts to delete all
links. However, link deletion only executes when arvif->is_created is true.
As a result, ahvif retains a stale entry of arvif that is initialized but
not created.

When a new arvif is initialized with the same link id, this stale mapping
triggers the following WARN_ON.

Fix this issue by unassigning the link vif and clearing ahvif->links_map
if arvif is only initialized but not created.
