r6040: Fix multicast list iteration when hash filter is used

This was fixed in mainline by the interface change made in commit
f9dcbcc9e338d08c0f7de7eba4eaafbbb7f81249.

After walking the multicast list to set up the hash filter, this
function will walk off the end of the list when filling the
exact-match entries.  This was fixed in mainline by the interface
change made in commit f9dcbcc9e338d08c0f7de7eba4eaafbbb7f81249.
