[KDVM] Fix definition of RtlEqualMemory() (#6988)
Comply with the standard documented behaviour:

https://learn.microsoft.com/en-us/windows-hardware/drivers/ddi/wdm/nf-wdm-rtlequalmemory#return-value
> RtlEqualMemory returns TRUE if Source1 and Source2 are equivalent; otherwise, it returns FALSE.

and
https://learn.microsoft.com/en-us/windows-hardware/drivers/ddi/wdm/nf-wdm-rtlcomparememory#return-value
> [...] If all bytes match up to the specified Length value, the Length value is returned.
