dm vdo: update min_heap_callbacks to use default builtin swap

Browse source 
Replace the swp function pointer in the min_heap_callbacks of dm-vdo with
NULL, allowing direct usage of the default builtin swap implementation. 
This modification simplifies the code and improves performance by removing
unnecessary function indirection.
