Fix gc_page_sweep when last bitmap plane is not used
Depending on alignment, the last bitmap plane may not used. Then it will
appear as if all of the objects on that plane is unmarked, which will
cause a buffer overrun when we try to free the object. This commit
changes the loop to calculate the number of planes used
(bitmap_plane_count).
