[Bug #18014] Fix rb_gc_force_recycle unmark before sweep

Browse source 
If we force recycle an object before the page is swept, we should clear
it in the mark bitmap. If we don't clear it in the bitmap, then during
sweeping we won't account for this free slot so the `free_slots` count
of the page will be incorrect.
