wifi: iwlwifi: mld: refactor purging async notifications

To cancel all async notifications, we need to:
- cancel async_handlers_wk
- empty async_handlers_list

Instead of having the callers to do both, do it in
iwl_mld_purge_async_handlers_list and rename it accordingly.

Note that the caller iwl_cleanup_mld didn't cancel the work, but it is
harmless.
