Maninder Singh 30cee1e486 lib/list_debug.c: add object information in case of invalid object
As of now during link list corruption it prints about cluprit address and
its wrong value, but sometime it is not enough to catch the actual issue
point.

If it prints allocation and free path of that corrupted node, it will be a
lot easier to find and fix the issues.

Adding the same information when data mismatch is found in link list
debug data:

Moved prototype of mem_dump_obj() to bug.h, as mm.h can not be included in
bug.h.
