Currently auth state machine ML info is set only when the it is created
newly. However, if the association is tried again, the state machine will
exist already and hence the ML info will not be refreshed. This leads to
an issue where if in the subsequent association request, the MLD info is
different than old info then validation of it will fail.
Fix this issue by refreshing the auth state machine's ML info every time
association request is handled.
