  -----------
  acc: Fix drop_accounting() (do not be a NOOP!)

The bug here was that `drop_accounting()` was building its bitmask as:

    flag_mask = types * flags;

... whereas it should have done the same as in `do_accounting()`:

    flag_mask = types + types * flags;
                -------
		^ the actual acc types to reset were missing!
