From: Johannes Berg <johannes.berg@xxxxxxxxx>
On older (pre-MLD API) devices, we started also calling
iwl_mvm_set_link_mapping()/iwl_mvm_unset_link_mapping(),
but of course not also iwl_mvm_remove_link(). Since the
link ID was only released in iwl_mvm_remove_link() this
causes us to run out of FW link IDs very quickly. Fix
it by releasing the link ID correctly.
Fixes: a8b5d4809b50 ("wifi: iwlwifi: mvm: Configure the link mapping for non-MLD FW")
