i40e: clean whole mac filter list

Browse Source 
Clean the whole mac filter list when resetting after an intermediate
add or delete push to the firmware.  The code had evolved from using
a list from the stack to a heap allocation, but the memset() didn't
follow the change correctly.  This now cleans the whole list rather
that just part of the first element.
