This occurs when a virtual allocated heap entry gets reallocated to a smaller
size. Part of the memory may be eligible for decommit or release in such a
case.

The code attempts to release part of the memory then, but ReactOS can't do a
partial release yet, so it fails. A decommit can be used, but
NtFreeVirtualMemory doesn't properly return how much memory has been
decommitted yet, so it would screw up the heap entry's metadata.

When the heap entry is free, the heap is destroyed or the process exits, the
memory does get properly released. In a nutshell: can be safely ignored until
the MM rewrite is complete.
