[PATCH 0/1] MR5056: ntdll: Fix DW_OP_abs absolute value warning on labs() for clang.

[Marc-Aurel Zent (＠mzent)]

Fixes the following warning on clang-15:

```
dlls/ntdll/unix/dwarf.h:915:45: warning: taking the absolute value of unsigned type 'ULONG_PTR' (aka 'unsigned long') has no effect [-Wabsolute-value]
        case DW_OP_abs:         stack[sp] = labs(stack[sp]); break;
                                            ^
dlls/ntdll/unix/dwarf.h:915:45: note: remove the call to 'labs' since unsigned values cannot be negative
        case DW_OP_abs:         stack[sp] = labs(stack[sp]); break;
                                            ^~~~
```

Despite what it says the existing code was functioning correctly already though AFAICT.
