memory tier: rename destroy_memory_type() to put_memory_type()

memory tier: rename destroy_memory_type() to put_memory_type()

It appears that destroy_memory_type() isn't a very good name because we
usually will not free the memory_type here.  So rename it to a more
appropriate name i.e.  put_memory_type().
