FILTER_SCHEDULE_THREAD is not a bit-value

That was the original plan, but I now plan to no longer allow that.  I think I 
posted a thread to that effect on arch@ several months ago.  However, in some 
patches I have to rework ithreads, I remove the bitmask bits and make the 
return value a simple enum of distinct values.

Also, your patch is not really correct I think, note that that code is only
in the !INTR_FITLER case, and we don't allow you to OR together those two
values in the INTR_FILTER case.
