beam_load.c: Remove useless call to next_heap_size()
The idea was probably to cause less fragmentation. Even if that would be true, it is irrelevant because the short-lived allocator that is used does not have any problems with fragmentation. In CodeNeed() we will simply double the size of the area used for code instead of using the next heap size.
