Expected, since we're doing:
            /* try valid parameters */
            rc = acmDriverClose(had, 0);
            ok(rc == MMSYSERR_NOERROR,
               "acmDriverClose(): rc = %08x, should be %08x\n",
               rc, MMSYSERR_NOERROR);

            /* try closing again */
            rc = acmDriverClose(had, 0);
            ok(rc == MMSYSERR_INVALHANDLE,
               "acmDriverClose(): rc = %08x, should be %08x\n",
               rc, MMSYSERR_INVALHANDLE);

Placeholder bug.
